[PM/AA] Hoist the AliasResult enum out of the AliasAnalysis class.
This will allow classes to implement the AA interface without deriving
from the class or referencing an internal enum of some other class as
their return types.
Also, to a pretty fundamental extent, concepts such as 'NoAlias',
'MayAlias', and 'MustAlias' are first class concepts in LLVM and we
aren't saving anything by scoping them heavily.
My mild preference would have been to use a scoped enum, but that
feature is essentially completely broken AFAICT. I'm extremely
disappointed. For example, we cannot through any reasonable[1] means
construct an enum class (or analog) which has scoped names but converts
to a boolean in order to test for the possibility of aliasing.
[1]: Richard Smith came up with a "solution", but it requires class
templates, and lots of boilerplate setting up the enumeration multiple
times. Something like Boost.PP could potentially bundle this up, but
even that would be quite painful and it doesn't seem realistically worth
it. The enum class solution would probably work without the need for
a bool conversion.

While these two enums do track mod/ref information and aliasing
information, they don't represent the exact same things as either the
mod/ref enums or the alias result enum in AA. They're definitions are
dominated by the structure of their lattice and the bit's various
semantics. This patch just calls them what they are and tries to spell
out usefully distinct names for these things.
This will clear the path for using a raw unscoped enum to represent some
of these concepts across LLVM's analysis library.

AsmPrinter: Rewrite initialization of DbgVariable, NFC
There are three types of `DbgVariable`:
- alloca variables, created based on the MMI table,
- register variables, created based on DBG_VALUE instructions, and
- optimized-out variables.
This commit reconfigures `DbgVariable` to make it easier to tell which
kind we have, and make initialization a little clearer.
For MMI/alloca variables, `FrameIndex.size()` must always equal
`Expr.size()`, and there shouldn't be an `MInsn`. For register
variables (with a `MInsn`), `FrameIndex` must be empty, and `Expr`
should have 0 or 1 element depending on whether it has a complex
expression (registers with multiple locations use `DebugLocListIndex`).
Optimized-out variables shouldn't have any of these fields.
Moreover, this separates DBG_VALUE initialization until after the
variable is created, simplifying logic in a future commit that changes
`collectVariableInfo()` to stop creating empty .debug_loc entries/lists.

Switch lowering: add heuristic for filling leaf nodes in the weight-balanced binary search tree
Sparse switches with profile info are lowered as weight-balanced BSTs. For
example, if the node weights are {1,1,1,1,1,1000}, the right-most node would
end up in a tree by itself, bringing it closer to the top.
However, a leaf in this BST can contain up to 3 cases, and having a single
case in a leaf node as in the example means the tree might become
unnecessarily high.
This patch adds a heauristic to the pivot selection algorithm that moves more
cases into leaf nodes unless that would lower their rank. It still doesn't
yield the optimal tree in every case, but I believe it's conservatibely correct.

Improve error handling of getRelocationAddend.
This patch changes getRelocationAddend to use ErrorOr and considers it an error
to try to get the addend of a REL section.
If, for example, a x86_64 file has a REL section, that file is corrupted and
we should reject it.
Using ErrorOr is not ideal since we check the section type once per relocation
instead of once per section.
Checking once per section would involve getRelocationAddend just asserting and
callers checking the section before iterating over the relocations.
In any case, this is an improvement and includes a test.

[ARM] Look through concat when lowering in-place shuffles (VZIP, ..)
Currently, we canonicalize shuffles that produce a result larger than
their operands with:
shuffle(concat(v1, undef), concat(v2, undef))
->
shuffle(concat(v1, v2), undef)
because we can access quad vectors (see PerformVECTOR_SHUFFLECombine).
This is useful in the general case, but there are special cases where
native shuffles produce larger results: the two-result ops.
We can look through the concat when lowering them:
shuffle(concat(v1, v2), undef)

concat(VZIP(v1, v2):0, :1)

dozens of VMOVs.

MIR Serialization: initialize the fields without the default initializers in yaml::MachineFunction
My commit r239790 which introduced serialization for simple machine function attributes didn't
initialize them when parsing because I have misread the documentation for YAML IO's mapOptional
method. The mapOptional method doesn't actually set the values to the values returned by the
default constructor for that type when the key value pair is missing, it just doesn't modify
those values, so they still contain the value that was set during initialization by the default
constructor. But the fields in yaml::MachineFunction with types like unsigned and bool are not
initialized by default, and thus they can still be uninitialized after mapOptional during parsing.

[X86] Refactor stack adjustments into X86FrameLowering::BuildStackAdjustment
Deduplicates some code and lets us use LEA on atom when adjusting the
stack around callee-cleanup calls. This is the only intended
functionality change.

[BranchFolding] Replace custom MachineInstr with MachineInstrExpressionTrait
While the hash functions are subtly different it shouldn't have an
impact. Instructions are checked with isIdenticalTo later.

[CallGraph] Teach the CallGraph about non-leaf intrinsics.
Summary:
Currently intrinsics don't affect the creation of the call graph.
This is not accurate with respect to statepoint and patchpoint
intrinsics -- these do call (or invoke) LLVM level functions.
This change fixes this inconsistency by adding a call to the external
node for call sites that call these non-leaf intrinsics. This coupled
with the fact that these intrinsics also escape the function pointer
they call gives us a conservatively correct call graph.
