This is suboptimal in several aspects, see the commented out assertion.
I need to talk to Daniel about this.

Fixed a bug in LiveInterval scaling (failure to scale VNI defs correctly), removed old TODO comments.

Fix support for inline asm input / output operand tying when operand spans across multiple registers (e.g. two i64 operands in 32-bit mode).

trip counts in more cases.

Generalize ScalarEvolution's isLoopGuardedByCond code to recognize
And and Or conditions, splitting the code out into an
isNecessaryCond helper function so that it can evaluate Ands and Ors
recursively, and make SCEVExpander be much more aggressive about
hoisting instructions out of loops.

test/CodeGen/X86/pr3495.ll has an additional instruction now, but
it appears to be due to an arbitrary register allocation difference.

createSCEV. Also, recognize UndefValue in createSCEV.

Change getIntegerSCEV's comment to avoid mentioning FP types,
and re-implement it in terms of getConstant instead of getUnknown.

and associate it with the FunctionDecl.

compile warnings.
