88eb89b89f [asm parser] Add support for predicating MnemonicAlias based on the assembler
variant/dialect.  Addresses a FIXME in the emitMnemonicAliases function.
Use and test case to come shortly.

8a6a7bb6a6 Cleanup patch:
Semantics of parameters named Index and Idx were inconsistent between
"include/llvm/IR/Attributes.h", "lib/IR/AttributeImpl.h" and
"lib/IR/Attributes.cpp": sometimes these were fixed 1-based indexes of IR
parameters (or AttributeSet::ReturnIndex for IR return values or
AttributeSet::FunctionIndex for IR functions), other times they were the
internal slot for storage in the underlying AttributeSetImpl. I renamed usage of
the former to "Index" and usage of the latter to "Slot" ("Slot" was already
being used consistently for the latter in a subset of cases)

bb1b63c483 This patch addresses two cleanup issues:
1. Verify::VerifyParameterAttrs in "lib/IR/Verifier.cpp" and
   AttrBuilder::removeFunctionOnlyAttrs in "lib/IR/Attributes.cpp" (only called
   by Verify::VerifyFunctionAttrs) separately maintained a list of function-only
   attribute types. I've consolidated the logic into a new function used for
   both cases in "lib/IR/Verifier.cpp", so this logic is in one place (other
   than the AsmParser front-end)

2. Various functions in "lib/IR/Verifier.cpp" passed AttributeSet around by
   reference needlessly, as it's just a handle to an immutable pimpl body.

43239078ad Two small cleanups for ELF's templates.
* We only ever specialize these templates with an instantiation of ELFType,
  so we don't need a template template.
* Replace LLVM_ELF_COMMA with just passing the individual parameters to the
  macro. This requires a second macro for when we only have ELFT, but that
  is still a small win.

21a01d1ea8 Make the host endianness check an integer constant expression.
I will remove the isBigEndianHost function once I update clang.

The ifdef logic is designed to
* not use configure/cmake to avoid breaking -arch i686 -arch ppc.
* default to little endian
* be as small as possible

It looks like sys/endian.h is the preferred header on most modern BSD systems,
but it is better to change this in a followup patch as machine/endian.h is
available on FreeBSD, OpenBSD, NetBSD and OS X.

4392f0f407 MI-Sched: schedule physreg copies.
The register allocator expects minimal physreg live ranges. Schedule
physreg copies accordingly. This is slightly tricky when they occur in
the middle of the scheduling region. For now, this is handled by
rescheduling the copy when its associated instruction is
scheduled. Eventually we may instead bundle them, but only if we can
preserve the bundles as parallel copies during regalloc.

Original message:

if it is extern and if it is scattered.

It also refactors the code a bit to use bit fields instead of shifts and
masks all over the place.

18d49acdab MC: Support COFF image-relative MCSymbolRefs
Add support for the COFF relocation types IMAGE_REL_I386_DIR32NB and
IMAGE_REL_AMD64_ADDR32NB for 32- and 64-bit respectively. These are
similar to normal 4-byte relocations except that they do not include
the base address of the image.

Image-relative relocations are used for debug information (32-bit) and
SEH unwind tables (64-bit).

A new MCSymbolRef variant called 'VK_COFF_IMGREL32' is introduced to
specify such relocations. For AT&T assembly, this variant can be accessed
using the symbol suffix '@imgrel'.
