[PATCH] D35888: Changed basic cost of Store operation on X86.

[Elena Demikhovsky via Phabricator via llvm-commits]

delena created this revision.

Store operation takes 2 UOps on X86 processors. The exact cost calculation affects several optimization passes including loop unroling.
This change compensates performance degradation caused by https://reviews.llvm.org/D34458 and shows improvements on some benchmarks.
