Fixups list for the instruction so the operand encoders can add to it as

This is both the conceptually correct place for it, as well as allowing it to be more aggressive.

llvm-svn: 118204

We could be more aggressive about making this work for a larger range of constants,
but this seems like a good start.

an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that

The problem was with how the addressing mode 5 encodes the offsets. This change
makes sure that the way offsets are handled in addressing mode 5 is consistent
throughout the MC code. It involves re-refactoring the "getAddrModeImmOpValue"
method into an "Imm12" and "addressing mode 5" version. But not to worry! The
majority of the duplicated code has been unified.

1. Fix pre-ra scheduler so it doesn't try to push instructions above calls to
   "optimize for latency". Call instructions don't have the right latency and
   this is more likely to use introduce spills.
2. Fix if-converter cost function. For ARM, it should use instruction latencies,
   not # of micro-ops since multi-latency instructions is completely executed
   even when the predicate is false. Also, some instruction will be "slower"
   when they are predicated due to the register def becoming implicit input.
