When a local virtual register is made global, make sure to clear any
existing kill flags.

This would previously get reported as the misleading "Virtual register
def doesn't dominate all uses."

The solution is a bit inefficient: it creates N checkers, one for each check, and
each check does a dispatch on the function name.  This is redundant, but we can fix
this once we have the proper ability to enable/disable subchecks.

Fixes <rdar://problem/11780180>.

RefreshCallGraph: ignore 'invoke intrinsic'. IntrinsicInst doesnt not recognize invoke, and shouldnt at this point, since the rest of LLVM codebase doesnt expect invoke of intrinsics

ignore 'invoke new' in isInstructionTriviallyDead, since most callers are not ready to handle invokes. instcombine will take care of this.

This was always part of the VMCore library out of necessity -- it deals
entirely in the IR. The .cpp file in fact was already part of the VMCore
library. This is just a mechanical move.

I've tried to go through and re-apply the coding standard's preferred
header sort, but at 40-ish files, I may have gotten some wrong. Please
let me know if so.

I'll be committing the corresponding updates to Clang and Polly, and
Duncan has DragonEgg.

Thanks to Bill and Eric for giving the green light for this bit of cleanup.
