BasicAA: Only query twice if the result of the more general query was MayAlias2013-03-26T18:07:53ZArnold Schwaighoferaschwaighofer@apple.com2013-03-26T18:07:53Zurn:sha1:742dbc1fc83f713e139a2745ebb34a97c11c43bd
This is a compile time optimization. Before the patch we would do two traversals
on each call to aliasGEP - one with a set size parameter one with UnknownSize.
We can do better by first checking the result of the alias query with
UnknownSize.
Only if this one returns MayAlias do we query a second time using size and type.
This recovers an about 7% compile time regression on spec/ammp.

Fix SCEV forgetMemoizedResults should search and destroy backedge exprs.2013-03-26T03:14:53ZAndrew Trickatrick@apple.com2013-03-26T03:14:53Zurn:sha1:e74c2e86cb405963ba9c4043a1d0ca00b8f85fbe
Fixes PR15570: SEGV: SCEV back-edge info invalid after dead code removal.
Indvars creates a SCEV expression for the loop's back edge taken
count, then determines that the comparison is always true and
removes it.
When loop-unroll asks for the expression, it contains a NULL
SCEVUnknkown (as a CallbackVH).
forgetMemoizedResults should invalidate the loop back edges expression.

Support in AAEvaluator to print alias queries of loads/stores with TBAA tags.2013-03-22T22:34:41ZManman Renmren@apple.com2013-03-22T22:34:41Zurn:sha1:a2e3834d1644889484ef3a8a94189b7369e3eaf9
Add "evaluate-tbaa" to print alias queries of loads/stores. Alias queries
between pointers do not include TBAA tags.
Add testing case for "placement new". TBAA currently says NoAlias.

Check whether a pointer is non-null (isKnownNonNull) in isKnownNonZero.2013-03-18T21:23:25ZManman Renmren@apple.com2013-03-18T21:23:25Zurn:sha1:90842427b2f6ab5c0aab6049fd9177033101847f
This handles the case where we have an inbounds GEP with alloca as the pointer.
This fixes the regression in PR12750 and rdar://13286434.
Note that we can also fix this by handling some GEP cases in isKnownNonNull.
