DataLayout is no longer optional. It was initialized with or without
a DataLayout, and the DataLayout when supplied could have been the
one from the TargetMachine.

Summary:
Avoid using the TargetMachine owned DataLayout and use the Module owned
one instead. This requires passing the DataLayout up the stack to
ComputeValueVTs().

Column information is present in CodeView when the line table subsection
has bit 0 set to 1 in it's flags field. The column information is
represented as a pair of 16-bit quantities: a starting and ending
column. This information is present at the end of the chunk, after all
the line-PC pairs.

Fix some places where the word consecutive is used but the code really
means constant-stride (i.e. not just unit stride).

This commit ([LAA] Fix estimation of number of memchecks) regressed the
logic a bit. We shouldn't quit the analysis if we encounter a pointer
without known bounds *unless* we actually need to emit a memcheck for
it.
The original code was using NumComparisons which is now computed
differently. Instead I compute NeedRTCheck from NumReadPtrChecks and
NumWritePtrChecks.
As side note, I find the separation of NeedRTCheck and CanDoRT
confusing, so I will try to merge them in a follow-up patch.

Place all code corresponding to a run-time check in one place.
Previously we generated some code, then proceeded to a next check, then
finished the code for the first check (like splitting blocks and
generating branches). Now the code for generating a check is
self-contained.

A recent patch added calls to isInstructionTriviallyDead without the
corresponding dependency on TransformUtils.

All the usual X86 target-specific conventions are collapsed to the
normal Win64 convention, but the custom conventions like GHC and webkit
should not be.
Previously we would assume that the caller allocated 32 bytes of shadow
space for us, which is not how webkit_jscc or other custom conventions
are supposed to work.
Based on a patch by peavo@outlook.com.
Fixes PR24051.

No support for the symbol table yet (but will hopefully add it today).
We always use the long filename format so that we can align the member,
which is an advantage of the BSD format.

This commit changes the type of the field 'Name' in the struct
'yaml::MachineBasicBlock' from 'std::string' to 'yaml::StringValue'. This change
allows the MIR parser to report errors related to the MBB name with the proper
source locations.

The inferred output file name is based on the first input file, not the
first one with extension .obj. The output file was also being written to
the wrong directory; it needs to be written to whichever directory on the
libpath it was found in. This change fixes both issues.

r239285 ([LoopAccessAnalysis] Teach LAA to check the memory dependence
between strided accesses.) introduced a new case under
MemoryDepChecker::isDependent. We normally have debug output for each
case.

The 32-bit lowering assumed that WinEHPrepare had this invariant.
WinEHPrepare did it for C++, but not SEH. The result was that we would
insert calls to llvm.x86.seh.restoreframe in normal basic blocks, which
corrupted the frame pointer.

There's no reason to be able to mutate `MCSubtargetInfo` in
`getDeprecationInfo()`. Constify the reference.

- Implement copying ASR to/from GPR regs.
- Mark ASRs as non-allocatable, so it won't try to arbitrarily use
them inappropriately.
- Instead of inserting explicit WRASR/RDASR nodes in the MUL/DIV
routines, just do normal register copies.
- Also...mark div as using Y, not just writing it.
Added a test case with some code which previously died with an
assertion failure (with -O0), or produced wrong code (otherwise).
(Third time's the charm?)
