ppc: Fix record of HTM instructions
The patch fixes the record support of Hardware Transactional Memory
instructions on Power. It also solves a large number of unexpected failures
from gdb.reverse testcases sigall-precsave.exp and sigall-reverse.exp that
occur on distros which glibc uses HTM instructions.
