Fix ARM FastISel tests, as a first step to enabling ARM FastISel ARM FastISel is currently only enabled for iOS non-Thumb1, and I'm working on enabling it for other targets. As a first step I've fixed some of the tests. Changes to ARM FastISel tests: - Different triples don't generate the same relocations (especially movw/movt versus constant pool loads). Use a regex to allow either. - Mangling is different. Use a regex to allow either. - The reserved registers are sometimes different, so registers get allocated in a different order. Capture the names only where this occurs. - Add -verify-machineinstrs to some tests where it works. It doesn't work everywhere it should yet. - Add -fast-isel-abort to many tests that didn't have it before. - Split out the VarArg test from fast-isel-call.ll into its own test. This simplifies test setup because of --check-prefix.

Re-committing r130454, which does not in fact break anything. Fix a rather obscure crash caused by ARM fast-isel generating code which redefines a register. rdar://problem/9338332 . git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130539 91177308-0d34-0410-b5e6-96231b3b80d8 2011-04-29 21:22:56 +00:00			`; This isn't exactly a useful set of command-line options, but check that it`
