4cddfd9b6f Don't mark registers dead here when processing nodes with MVT::Flag
results. This works around a problem affecting targets which rely on
MVT::Flag to handle physical register defs.

1107c63efe Optimize around the fact that pred_iterator is slow: instead of sorting
PHI operands by the predecessor order, sort them by the order used by the
first PHI in the block. This is still suffucient to expose duplicates.

9c41fa87ea Updates to the ARM target assembler for llvm-mc per review comments from
Daniel Dunbar.
- Reordered the fields in the ARMOperand Mem struct to make the struct smaller.
Making bool's into 1 bit fields and put the MCExpr* fields adjacent to each
other.
- Fixed a number of places in ARMAsmParser.cpp so they have doxygen comments.
- Change the name of ARMAsmParser::ParseRegister() to MaybeParseRegister and
added the bool ParseWriteBack parameter.
- Changed ARMAsmParser::ParseMemory() to call MaybeParseRegister().
- Added ARMAsmParser::ParseMemoryOffsetReg to factor out parsing the offset of a
memory operand.  And use it for both parsing both preindexed and post indexing
addressing forms in ARMAsmParser::ParseMemory.
- Changed the first argument to ParseShift() to a reference.
- Changed ParseShift() to check for Rrx first and return to reduce nesting.

dac8bde235 if basic blocks are destroyed while there are *just* BlockAddress' hanging
around, then zap them.  This is analogous to dangling constantexprs hanging
off functions.

This reduces codesize on a variety of codes by 1-2% on x86-64. It also
helps clean up after SSAUpdater.

to be eliminated.

0115e164ba Fix MachineLICM to use the correct virtual register class when
unfolding loads for hoisting.  getOpcodeAfterMemoryUnfold returns the
opcode of the original operation without the load, not the load
itself, MachineLICM needs to know the operand index in order to get
the correct register class. Extend getOpcodeAfterMemoryUnfold to
return this information.

1f22d6f131 When cross-building, the CFLAGS and CXXFLAGS are for the target, and don't
apply to the build tools. If we want to allow build tool flags input, we
should have separate inputs (BUILD_CFLAGS and BUILD_CXXFLAGS, perhaps).

c1382b745f This fixes functions like
void f (int a1, int a2, int a3, int a4, int a5,...)

In ARMTargetLowering::LowerFormalArguments if the function has 4 or
more regular arguments we used to set VarArgsFrameIndex using an
offset of 0, which is only correct if the function has exactly 4
regular arguments.
