  A few fixes for PIC instrumentation on power

1. Fix PC-relative load and store of variables
2. The preamble of PIE uses R12 to set up R2. However,
when generating intra-module calls, Dyninst does not
set up R12 and will call the global entry, causing R2 to
be incorrect. Since there is no need to change R2 for
intra-module calls, we should call the local entry
