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.

Fix a crazy canonical-types bug because canonicalizing a
...
dependently-sized array type with a given expression might end up
returning a non-canonical type; see through that non-canonical type to
the underlying canonical type. Yes, I have a test case; no, I can't
reduce it to the point where it's worth checking in :(

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.

Fix MachineLICM to use the correct virtual register class when

opcode of the original operation without the load, not the load
itself, MachineLICM needs to know the operand index in order to get
