might be deliberate "one time" leaks, so that leak checkers can find them.
This is a reapply of r160602 with the fix that this time I'm committing the
code I thought I was committing last time; the I->eraseFromParent() goes
*after* the break out of the loop.

Change llvm_unreachable in SplitVectorOperand to report_fatal_error. Keeps release builds from crashing if code uses an intrinsic with an illegal type.

Change llvm_unreachable in SplitVectorResult to report_fatal_error. Keeps release builds from crashing if code uses an intrinsic with an illegal type. For instance 256-bit AVX intrinsics without having AVX enabled.

In current implementation, JIT should run only on host.

r160529 that was subsequently reverted. The fix was to not call
GV->eraseFromParent() right before the caller does the same. The existing
testcases already caught this bug if run under valgrind.

This pass no longer requires that the global pointer value be saved to the
stack or register since it uses bal instruction to compute branch distance.

baby steps toward fixing some problems with inbound GEPs that overflow, as discussed 2 months ago or so.
Make sure we do not emit index computations with NSW flags so that we dont get an undef value if the GEP overflows

move the bounds checking pass to the instrumentation folder, where it belongs. I dunno why in the world I dropped it in the Scalar folder in the first place.
No functionality change.

Remove unused private member variables uncovered by the recent changes to clang's -Wunused-private-field.

LiveRangeEdit::foldAsLoad() can eliminate a register by folding a load
into its only use. Only do that when the load is safe to move, and it
won't extend any live ranges.

This fixes PR13414.

CI's name, and then used the StringRef pointing at its old name. I'm
fixing it by storing the name in a std::string, and hoisting the
renaming logic to happen always. This is nicer anyways as it will allow
the upgraded IR to have the same names as the input IR in more cases.

Another bug found by AddressSanitizer. Woot.

PHIElimination splits critical edges when it predicts it can resolve
interference and eliminate copies. It doesn't split the edge if the
interference wouldn't be resolved anyway because the phi-use register is
live in the critical edge anyway.

Teach PHIElimination to split loop exiting edges with interference, even
if it wouldn't resolve the interference. This removes the necessary
copies from the loop, which is still an improvement from injecting the
copies into the loop.

The test case demonstrates the improvement. Before:

LBB0_1:
  cmpb  $0, (%rdx)
  leaq  1(%rdx), %rdx
  movl  %esi, %eax
  je  LBB0_1

After:

LBB0_1:
  cmpb  $0, (%rdx)
  leaq  1(%rdx), %rdx
  je  LBB0_1

  movl  %esi, %eax

GetBestDestForJumpOnUndef() assumes there is at least 1 successor, which isn't
true if the block ends in an indirect branch with no successors. Fix this by
bailing out earlier in this case.

[asan] make sure that the crash callbacks do not get merged (Chandler's idea: insert an empty InlineAsm). Change the order in which the new BBs are inserted: the slow path BB is insert between old BBs, the crash BB is inserted at the end. Don't create an empty BB (introduced by recent commits). Update the test. The experimental code that does manual crash callback merge will most likely be deleted later.

Don't use implicit register operands to calculate L-bit for AVX instructions. Needed because super reg defs and kills are added as implicit operands on 128-bit instructions. Fixes PR13349. Patch by Jose Fonseca.
