alignment of globals to the preferred alignment, but only when
there is no section specified on the global (by far the common
case).

Changed signature of GenerateMessageSend() function to pass the ObjCInterfaceDecl for class messages and removed the boolean IsClassMessage argument, which wasn't used anywhere.

Emitted some metadata on message sends to allow a later pass to do some speculative inlining of class methods (GNU runtime).  Speculative inlining of instance methods requires type feedback to be useful (work in progress), but for class methods it works quite nicely.

While lowering dbg_declare, emit DBG_VALUE machine instruction if alloca matching llvm.dbg.declare intrinsic is missing.

update them. Computing kill flags is notoriously difficult, and the coalescer
would get it wrong sometimes, and it would completely skip physical registers.

Now we simply remove kill flags based on the live intervals after coalescing.
This is a few percent slower, but now we get correct kill flags for physical
registers after coalescing.

This instruction would crash the pass:

  INLINEASM <es:foo $0 $1>, 9, %FP0<kill>, 9, %FP0<kill>, 14, %EFLAGS<earlyclobber,def,dead>

Now it doesn't.

I wasn't able to reduce to anything useful.

Rather than having a ton of patterns for double shift instructions, e.g. SHLD16rrCL, just perform custom dag combine to form x86 specific dag so they match to the same pattern. This also makes sure later dag combine do not cause isel to miss them (e.g. promoting i16 to i32).

The dependence model isn't complete yet, but it's already much more
