cd38485b8a Duncan pointed out that if the alignment isn't explicitly specified, it defaults to the ABI alignment. Given that, make this code a bit more aggressive in such cases.

b266cd0e98 Fix for PR12090: clear def maps of aliases when visiting a copy. e.g.

7b25ecf6ad ARM BL/BLX instruction fixups should use relocations. 
We on the linker to resolve calls to the appropriate BL/BLX instruction
to make interworking function correctly. It uses the symbol in the
relocation to do that, so we need to be careful about being too clever.

To enable this for ARM mode, split the BL/BLX fixup kind off from the
unconditional-branch fixups.

62c4d9799f Add a MachineOperand iterator class. 
The MIOperands iterator can visit operands on a single instruction, or
all operands in a bundle.  This simplifies code like the register
allocator that treats bundles as a set of operands.

5583e30818 The value numbering function is recursive, so it is possible for multiple new 
value numbers to be assigned when calculating any particular value number.
Enhance the logic that detects new value numbers to take this into account,
for a tiny compile time speedup.  Fix a comment typo while there.

669011f50b When performing a conditional branch depending on the value of a comparison 
%cmp (eg: A==B) we already replace %cmp with "true" under the true edge, and
with "false" under the false edge.  This change enhances this to replace the
negated compare (A!=B) with "false" under the true edge and "true" under the
false edge.  Reported to improve perlbench results by 1%.
