+1 flip the checks
Add a common CHECK as well to merge some of the cases:
```
# RUN: llc < %s -mtriple=x86_64-- -mattr=+no-bypass-delay-mov -run-pass=x86-fixup-inst-tuning | FileCheck %s --check-prefixes=CHECK,NODELAY
# RUN: llc < %s -mtriple=x86_64-- -mattr=-no-bypass-delay-mov -run-pass=x86-fixup-inst-tuning | FileCheck %s --check-prefixes=CHECK,MOV
```
