[PATCH] D38533: [CGP]Restrict complex select/phi case for optimizeMemoryInst

[Serguei Katkov via Phabricator via llvm-commits]

skatkov created this revision.

This patch is actually a preparation for extension of the scope of optimizeMemoryInst optimization.
For now it does nothing but disable in future implementation the complex cases like
Select of Phi/Select or Phi from Select.
