Alina Sbirlea beb9993d96 [MSSA] Update test with more detailed and resilient checks. [NFC] 2020-08-05 16:46:44 -07:00
Arthur Eubanks 4103f4a936 [MSSA][NewPM] Handle tests with -print-memoryssa 
-print-memoryssa in legacy PM is print<memoryssa> in NPM.
Pin tests with -print-memoryssa to legacy PM.
Add corresponding tests for NPM where missing.
This fixes "unknown pass name 'print-memoryssa'".

Some tests still fail in Analysis/MemorySSA due to other passes that
haven't been ported.

pr43427.ll and pr43438.ll required adding -aa-pipeline=basic-aa,
-loop-simplify (since it doesn't run on legacy PM by default), and
decrementing some of the MemoryPhi numbers.

Alina Sbirlea 24ae5ce54b [MemorySSA] Update Phi creation when inserting a Def. 
MemoryPhis should be added in the IDF of the blocks newly gaining Defs.
This includes the blocks that gained a Phi and the block gaining a Def,
if the block did not have one before.
Resolves PR43427.
