0b23dc0cc8 Fixed a bug in the PBQP allocator's findCoalesces method. 
Previously spill registers, whose def indexes are not defined, would sometimes be improperly marked as coalescable with conflicting registers. The new findCoalesces routine conservatively assumes that any register with at least one undefined def is not coalescable with any register it interferes with.

1926b648e1 Add a new pass to do llvm.objsize lowering using SCEV. 
Initial skeleton and SCEVUnknown lowering implemented,
the rest should come relatively quickly.  Move testcase
to new directory.

Move pass to right before SimplifyLibCalls - which is
moved down a bit so we can take advantage of a few opts.

3a3134ab12 use a c-style cast instead of reinterpret-cast, as sometimes the 
cast needs to adjust for a vtable pointer when going from base to
derived type (when the base doesn't have a vtable but the
derived type does).

618f17702d When CodeGen'ing unoptimized code, there may be unfolded constant expressions
