[XRay] Lazily compute MachineLoopInfo instead of requiring it.
Summary:
Currently X-Ray Instrumentation pass has a dependency on MachineLoopInfo

even if X-Ray is not used. This patch changes it to a lazy computation
to save compile time by avoiding these redundant computations.

[Hexagon] Improve scheduling heuristic for large basic blocks
This patch changes the isLatencyBound heuristic to look at the
path length based upon the number of packets needed to schedule
a basic block. For small basic blocks, the heuristic uses a small
threshold for isLatencyBound. For large basic blocks, the
heuristic uses a large threshold.
The goal is to increase the priority of an instruction in a small
basic block that has a large height or depth relative to the code
size. For large functions, the height and depth are ignored
because it increases the live range of a register and causes more
spills. That is, for large functions, it is more important to
schedule instructions when available, and attempt to keep the defs
and uses closer together.

[CGP] Avoid segmentation fault when doing PHI node simplifications
Summary:
Made PHI node simplifiations more robust in several ways:
- Minor refactoring to let the SimplificationTracker own the
sets with new PHI/Select nodes that are introduced. This is
maybe not mapping to the original intention with the
SimplificationTracker, but IMHO it encapsulates the logic behind
those sets a little bit better.
- MatchPhiNode can sometimes populate the Matched set with
several entries, where it maps one PHI node to different candidates
for replacement. The Matched set is changed into a SmallSetVector
to make sure we get a deterministic iteration when doing
the replacements.
- As described above we may get several different replacements
for a single PHI node. The loop in MatchPhiSet that is doing
the replacements could end up calling eraseFromParent several
times for the same PHI node, resulting in segmentation faults.
This problem was supposed to be fixed in rL327250, but due to
the non-determinism(?) it only appeared to be fixed (I still
got crashes sometime when turning on/off -print-after-all etc
to get different iteration order in the DenseSets).
With this patch we follow the deterministic ordering in the
Matched set when replacing the PHI nodes. If we find a new
replacement for an already replaced PHI node we replace the
new replacement by the old replacement instead. This is quite
similar to what happened in the rl327250 patch, but here we
also recursively verify that the old replacement hasn't been
replaced already.
- It was really hard to track down the fault described above
(segementation fault due to doing eraseFromParent multiple
times for the same instruction). The fault was intermittent and
small changes in the code, or simply turning on -print-after-all
etc could make the problem go away. This was basically due to
the iteration over PhiNodesToMatch in MatchPhiSet no being
deterministic. Therefore I've changed the data structure for
the SimplificationTracker::AllPhiNodes into an SmallSetVector.
This gives a deterministic behavior.

This addresses a shortcoming of per-symbol materialization: If a
MaterializationUnit (/SymbolSource) wants to materialize more symbols than
requested (which is likely: most materializers will want to materialize whole
modules) then it needs a way to notify the symbol table about the extra symbols
being materialized. This process (checking what has been requested against what
is being provided and notifying the symbol table about the difference) has to
be repeated at every level of the JIT stack. Making materialization
all-or-nothing eliminates this issue, simplifying both materializer
implementations and the symbol table (VSO class) API. The cost is that
per-symbol materialization (e.g. for individual symbols in a module) now
requires multiple MaterializationUnits.

[MachineOutliner] AArch64: Emit CFI instructions when outlining calls
When outlining calls, the outliner needs to update CFI to ensure that, say,
exception handling works. This commit adds that functionality and adds a test
just for call outlining.
Call outlining stuff in machine-outliner.mir should be moved into
machine-outliner-calls.mir in a later commit.

Support embedding natvis files in PDBs.
Natvis is a debug language supported by Visual Studio for
specifying custom visualizers. The /NATVIS option is an
undocumented link.exe flag which will take a .natvis file
and "inject" it into the PDB. This way, you can ship the
debug visualizers for a program along with the PDB, which
is very useful for postmortem debugging.
This is implemented by adding a new "named stream" to the
PDB with a special name of /src/files/<natvis file name>
and simply copying the contents of the xml into this file.
Additionally, we need to emit a single stream named
/src/headerblock which contains a hash table of embedded
files to records describing them.
This patch adds this functionality, including the /NATVIS
option to lld-link.

This patch prevents DBG_VALUE instructions from influencing

influence on code generation. The result was that certain code
compiled with '-g -O2' would differ from that compiled with '-O2'
alone. It seems that the original logic, accounting for DBG_VALUE,
was influencing the placement of an IMPLICIT_DEF which had a later

TableGen: Check the dynamic type of !cast<Rec>(string)
Summary:
The docs already claim that this happens, but so far it hasn't. As a
consequence, existing TableGen files get this wrong a lot, but luckily
the fixes are all reasonably straightforward.
To make this work with all the existing forms of self-references (since
the true type of a record is only built up over time), the lookup of
self-references in !cast is delayed until the final resolving step.

TableGen: Explicitly test some cases of self-references and !cast errors
Summary:
These are cases of self-references that exist today in practice. Let's
add tests for them to avoid regressions.
The self-references in PPCInstrInfo.td can be expressed in a simpler
way. Allowing this type of self-reference while at the same time
consistently doing late-resolve even for self-references is problematic
because there are references to fields that aren't in any class. Since
there's no need for this type of self-reference anyway, let's just
remove it.

TableGen: Remove the cast-from-string-to-variable-reference feature
Summary:
Cast-from-string for records isn't going away, but cast-from-string for
variables is a pretty dodgy feature to have, especially when referencing
template arguments. It's doubtful that this ever worked in a reliable
way, and nobody seems to be using it, so let's get rid of it and get
some related cleanups.

[llvm-mca] Add pipeline stall events.
This patch introduces a new class named HWStallEvent (see HWEventListener.h),
and updates the event listener interface. A HWStallEvent represents a pipeline
stall caused by the lack of hardware resources. Similarly to HWInstructionEvent,
the event type is an unsigned, and the exact meaning depends on the subtarget.
At the moment, HWStallEvent supports a few generic dispatch events.
The main goals of this patch is to remove the logic that counts dispatch stalls
from the DispatchUnit to the BackendStatistics view.
Previously, DispatchUnit was responsible for counting and classifying dispatch
stall events. With this patch, we delegate the task of counting and classifying
stall events to the listeners (i.e. in our case, it is view
"BackendStatistics"). So, the DispatchUnit doesn't have to do extra
(unnecessary) bookkeeping.
This patch also helps futher simplifying the Backend interface. Now class
BackendStatistics no longer has to query the Backend interface to obtain the
number of dispatch stalls. As a consequence, we can get rid of all the
'getNumXXX()' methods from class Backend.
The long term goal is to remove all the remaining dependencies between the
Backend and the BackendStatistics interface.

This is important, because these pointers are dereferenced twice
