cmake: Set LINK_POLLY_INTO_TOOLS to ON
With Polly checked into LLVM it was since a long time possible to compile
clang/opt/bugpoint with Polly support directly linked in, instead of only
providing Polly as a separate loadable module. This commit switches the
default from providing Polly as a module to linking Polly into tools, such
that it becomes unnecessary to load the Polly module when playing with Polly.
Such configuration has shown a lot more convenient for day-to-day Polly use.
This change does not impact the default behavior of any tool, if Polly is not
explicitly enabled when calling clang/opt/bugpoint Polly does not affect
compilation.
This change also does not impact normal LLVM/clang checkouts that do not
contain Polly.

AMDGPU/SI: Assembler: Unify parsing/printing of operands.
Summary:
The goal is for each operand type to have its own parse function and
at the same time share common code for tracking state as different
instruction types share operand types (e.g. glc/glc_flat, etc).
Introduce parseAMDGPUOperand which can parse any optional operand.
DPP and Clamp/OMod have custom handling for now. Sam also suggested
to have class hierarchy for operand types instead of table. This
can be done in separate change.
Remove parseVOP3OptionalOps, parseDS*OptionalOps, parseFlatOptionalOps,
parseMubufOptionalOps, parseDPPOptionalOps.
Reduce number of definitions of AsmOperand's and MatchClasses' by using common base class.
Rename AsmMatcher/InstPrinter methods accordingly.
Print immediate type when printing parsed immediate operand.
Use 'off' if offset/index register is unused instead of skipping it to make it more readable (also agreed with SP3).
Update tests.

Dead phi nodes are needed for code motion (such as copy propagation),
where a new use would be placed in a location that would be dominated
by a dead phi. Such a transformation is not legal for copy propagation,
and the existence of the phi would prevent it, but if the phi is not

Reset the TopRPTracker's position in ScheduleDAGMILive::initQueues
ScheduleDAGMI::initQueues changes the RegionBegin to the first non-debug

and it does reset the TopTPTracker in its schedule method. Any derived,
target-specific scheduler will need to do it as well, but the TopRPTracker
is only exposed as a "const" object to derived classes. Without the ability
to modify the tracker directly, this leaves a derived scheduler with a
potential of having the TopRPTracker out-of-sync with the CurrentTop.

Parse module information from DBI stream.
This gets more data out of the DBI strema of the PDB. In
particular it extracts the metadata for the list of modules
(compilands) that this PDB contains info about, and adds support
for dumping these fields to llvm-pdbdump.

[ImplicitNullChecks] Properly update the live-in of the block of the memory operation.
We basically replace:
HoistBB:
cond_br NullBB, NotNullBB
NullBB:
...
NotNullBB:
<reg> = load
into
HoistBB
<reg> = load_faulting_op NullBB
uncond_br NotNullBB
NullBB:
...
NotNullBB: ## <reg> is now live-in of NotNullBB
...
This partially fixes the machine verifier error for
test/CodeGen/X86/implicit-null-check.ll, but it still fails because
of the implicit CFG structure.

[PGO] Promote indirect calls to conditional direct calls with value-profile
This patch implements the transformation that promotes indirect calls to
conditional direct calls when the indirect-call value profile meta-data is
available.

it in a regression test, but I'm assuming there's some reason this

For compilations with no explicit cpu specified, this exhibits
nice gains on Silvermont, with neutral performance on big cores.
