[PPC] Adjust some PowerPC tests to account for presence/absence of VSX Patch by Bill Seurer; committed on his behalf. These test cases generate slightly different code sequences when VSX is activated and thus fail. The update turns off VSX explicitly for the existing checks and then adds a second set of checks for most of them that test the VSX instruction output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@220019 91177308-0d34-0410-b5e6-96231b3b80d8 2014-10-17 01:41:22 +00:00			`; RUN: llc < %s -mattr=-vsx -march=ppc32 -mtriple=powerpc-apple-darwin \| grep "fabs f1, f1"`

Refactor and check "onlyReadsMemory" before optimizing builtins. This patch is mostly just refactoring a bunch of copy-and-pasted code, but it also adds a check that the call instructions are readnone or readonly. That check was already present for sin, cos, sqrt, log2, and exp2 calls, but it was missing for the rest of the builtins being handled in this code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161282 91177308-0d34-0410-b5e6-96231b3b80d8 2012-08-03 23:29:17 +00:00			`%tmp2 = tail call double @fabs( double %f ) readnone ; <double> [#uses=1]`
