627c00b663 Add "mayHaveSideEffects" and "neverHasSideEffects" flags to some instructions. I 
based what flag to set on whether it was already marked as
"isRematerializable". If there was a further check to determine if it's "really"
rematerializable, then I marked it as "mayHaveSideEffects" and created a check
in the X86 back-end similar to the remat one.

43ad6b3e0d Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.

X86CodeEmitter.cpp:378: failed assertion `0 && "Immediate size not set!"'

I *think* this is right, but Evan, please verify.  It also looks like
CMPSDrr and maybe others are missing this info.  Evan, plz investigate.

ece2c04d53 Make instcombine promote inline asm calls to 'nounwind' 
calls.  Remove special casing of inline asm from the
inliner.  There is a potential problem: the verifier
rejects invokes of inline asm (not sure why).  If an
asm call is not marked "nounwind" in some .ll, and
instcombine is not run, but the inliner is run, then
an illegal module will be created.  This is bad but
I'm not sure what the best approach is.  I'm tempted
to remove the check in the verifier...
