[llvm] [NFC][PowerPC] Merge ppc64 encoding error tests (PR #169669)

[Lei Huang via llvm-commits]

https://github.com/lei137 created https://github.com/llvm/llvm-project/pull/169669

Based on the RUN lines, there is actually no need for different versions of these error files since no cpu specific 
option needed.  Combine to reduce confusion and maintenance as these are not huge files.
