s390/nmi: use vector instruction macros instead of byte patterns
Use vector instruction macros instead of byte patterns to increase
readability. The generated code is nearly identical:
- 1e8: e7 0f 10 00 00 36 vlm %v0,%v15,0(%r1)
- 1ee: e7 0f 11 00 0c 36 vlm %v16,%v31,256(%r1)
+ 1e8: e7 0f 10 00 30 36 vlm %v0,%v15,0(%r1),3
+ 1ee: e7 0f 11 00 3c 36 vlm %v16,%v31,256(%r1),3
By using the VLM macro the alignment hint is automatically specified
too. Even though from a performance perspective it doesn't matter at
all for the machine check code, this shows yet another benefit when
using the macros.
