Bob Wilson fe61fb1e10 Add a new pass on machine instructions to optimize away PHI cycles that ...

reduce down to a single value.  InstCombine already does this transformation
but DAG legalization may introduce new opportunities.  This has turned out to
be important for ARM where 64-bit values are split up during type legalization:
InstCombine is not able to remove the PHI cycles on the 64-bit values but
the separate 32-bit values can be optimized.  I measured the compile time 
impact of this (running llc on 176.gcc) and it was not significant.

Assembler

Function-local metadata whose operands had been optimized to no longer refer to function-local IR were not getting written by BitcodeWriter; solution is for these metadata to be enumerated just like global metadata.
