[PATCH] D118663: [AArch64] Adds SUBS and ADDS instructions to the MIPeepholeOpt.

[Micah Weston via Phabricator via llvm-commits]

red1bluelost updated this revision to Diff 405806.
red1bluelost added a comment.

Ensures that optimizations only occur on EQ and NE.

Updates the peephole optimization to check subsequent instructions to ensure that
the condition is only used for EQ and NE cases. This is done after checking the
immediate value to avoid running unnecessarily.

Updates comments and naming in the code.

Adds tests that verify various instructions that would use the condition code.
Also a test for when the condition code is used in multiple instructions.
