The test should also likely have some FileCheck bits to validate the
output(?).

MC/Mach-O: Rewrite atom association to be a final pass we do in Finish(), instead of tracking as part of emission.

The memcmp will be optimized further and even the pathological case
'strstr(x, "x") == x' generates optimal code now.

Make post-ra scheduling, anti-dep breaking, and register scavenger (conservatively) aware of predicated instructions. This enables ARM to move if-conversion before post-ra scheduler.

the code in X86 that lowers a select instruction by splitting the MBBs. This
eliminates the need to check from the bottom up in an MBB for live pregs.

flag argument to addReg is not the same format as flags attached
to MachineOperand, although both have the same info.  I don't
think this actually mattered; the bootstrap failure did not
reproduce on the next run anyway.
