dereferencable -> dereferenceable

llvm-svn: 306210

When SelectionDAG expands memcpy (or memmove) call into a sequence of load and store instructions, it disregards dereferenceable flag even the source pointer is known to be dereferenceable.
This results in an assertion failure if SelectionDAG commonizes a load instruction generated for memcpy with another load instruction for the source pointer.
This patch makes SelectionDAG to set the dereferenceable flag for the load instructions properly to avoid the assertion failure.

This patch links LLVM back-ends into bugpoint the same way they are already
available in 'opt' and 'clang'. This resolves an inconsistency that allowed the
use of LLVM backends in loadable modules that run in 'opt', but that would
prevent the debugging of these modules with bugpoint due to unavailable /
unresolved symbols.

For e.g. In D31859, Polly requires the NVPTX back-end.

Summary:
m_CombineOr isn't very efficient. The code using it is also quite verbose.

This patch adds m_Shift and m_BitwiseLogic matchers to make the using code more concise and improve the match efficiency.

The intention of processFixupValue is not to redefine the semantics of
MCExpr. It is odd enough that a expression lowers to a PCRel MCExpr or
not depending on what it looks like. At least it is a local hack now.

I left a fix for anyone trying to figure out what producers should be
producing a different expression.

This should *really* be a llvm-mc test, but the parser is broken.
See PR33579 for the parser bug.

Summary:
InstCombine replaces large allocas with small globals consts causing buffer overflows
on valid code, see PR33372.

This fix permits this optimization only if the global is dereference for alloca size.

Fixes PR33372

processFixupValue is called on every relaxation iteration. applyFixup
is only called once at the very end. applyFixup is then the correct
place to do last minute changes and value checks.

While here, do proper range checks again for fixup_arm_thumb_bl. We
used to do it, but dropped because of thumb2. We now do it again, but
use the thumb2 range.

Original commit message:

  [mips] Fix register positions in the aui/daui instructions

  Swapped the position of the rt and rs register in the aui/daui
  instructions for mips32r6 and mips64r6. With this change, the format of
  the generated instructions complies with specifications and GCC.
  Patch by Milos Stojanovic.

We would return an error in getVaPtr if the RVA table being dumped was
the last data in the .rdata section. Avoid the issue by subtracting one
from the offset and adding it back to get an open interval again.

This reverts commit r306157.
It caused some timeouts in clang tests. Perhaps unreachable loops have
far too many phi nodes.
Reverting and investigating.
