755525ad23 There is this new "LLVM" compiler that supports __builtin_bswap but thinks it's gcc 4.2.

e1bcb440dc Add an option to disable codegen prepare critical edge splitting. In theory, PHI elimination is already doing all (most?) of the splitting needed. But machine-licm and machine-sink seem to miss some important optimizations when splitting is disabled.

65bffec2c2 Make dumpPassStructure be a PMDataManager abstraction, rather than
a Pass abstraction, since that's the level it's actually used at.
Rename Pass' dumpPassStructure to dumpPass.

This eliminates an awkward use of getAsPass() to convert a PMDataManager*
into a Pass* just to permit a dumpPassStructure call.

4861ed60ac Better handle alignment requirements for local objects in pre-regalloc frame
mapping. Have the local block track its alignment requirement, and then
apply that when the block itself is allocated. Previously, offsets could
get adjusted in PEI to be different, relative to one another, than the
block allocation thought they would be, which defeats the point of doing
the allocation this way. Continuing rdar://8277890

7d0e3c01f3 Revert r111031. The way LLVM defines loop invariance, the property of an
expression being loop invariant is not equivalent to the property of
properly dominating the loop header.

Other optimizations have also made this optimization less important.
