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.

Mehdi Amini 56228dabfa Redirect DataLayout from TargetMachine to Module in ComputeValueVTs()
Summary:
Avoid using the TargetMachine owned DataLayout and use the Module owned
one instead. This requires passing the DataLayout up the stack to
ComputeValueVTs().

DataLayout during compilation by using always the one owned by the

Adam Nemet 424edc6c80 [LAA] Revert a small part of r239295
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.

Reid Kleckner 4f21df2b96 [Win64] Only treat some functions as having the Win64 convention
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.

insert calls to llvm.x86.seh.restoreframe in normal basic blocks, which

James Y Knight f238d176eb [SPARC] Cleanup handling of the Y/ASR registers.
- 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?)
