Matthias Braun c045c557b0 Relax fast register allocator related test cases; NFC
- Relex hard coded registers and stack frame sizes
- Some test cleanups
- Change phi-dbg.ll to match on mir output after phi elimination instead
  of going through the whole codegen pipeline.

This is in preparation for https://reviews.llvm.org/D52010
I'm committing all the test changes upfront that work before and after
independently.

Jonas Paulsson 19380bae05 [SystemZ] Bugfix in expandRxSBG()
Csmith discovered a program that caused wrong code generation with -O0:

When handling a SIGN_EXTEND in expandRxSBG(), RxSBG.BitSize may be less than
the Input width (if a truncate was previously traversed), so maskMatters()
should be called with a masked based on the width of the sign extend result
instead.
