bc files for modules with a target triple that indicates they are for
darwin. The reader unconditionally handles this, and the writer could
turn this on for more targets if we care.
This change has two benefits for darwin:
1) it allows us to encode the cpu type of the file in an easy to read
place that doesn't require decoding the bc file.
2) it works around a bug (IMO) in darwin's AR where it is incapable of
handling files that are not a multiple of 8 bytes long. BC files
are only guaranteed to be multiples of 4 bytes long.

0.5909s (LV + Regalloc) to 0.421s (just regalloc).

This is a question of the debugging setup code not
being called at the right time, and it's called from
target-dependent code for some reason. I have only
attempted to fix Darwin, but I'm pretty sure it's
broken elsewhere; I'll leave that to people who can
test it.

soft float: experiments show that targets aren't
expecting this for results or for operands. Add
support select/select_cc result soft float and
correct operand soft float for these.

predecessor for multiple successors. Testcase here:

1) evaluate [v]fcmp true/false with undefs to true or false instead
of undef.
2) fix vector comparisons with undef to return a vector result instead
of i1
3) fix vector comparisons with evaluatable results to return vector
true/false instead of i1 true/false (PR2529)

MachineMemOperands. The pools are owned by MachineFunctions.
This drastically reduces the number of calls to malloc/free made
during the "Emit" phase of scheduling, as well as later phases
in CodeGen. Combined with other changes, this speeds up the
"instruction selection" phase of CodeGen by 10% in some cases.

This drastically reduces the number of calls to malloc/free made during
instruction selection, and improves memory locality.
