Contribution of PowerPC port (continuation of 422063005817143002 and 866843003)
This patch brings the ppc directories up to date with our repo. We have
removed 5 individual optimizations which require changes in both the ppc and common
directories so they can be more easily reviewed on their own in subsequent patches.

Subsequent patches will cover:
- individual optimizations for PPC (5)
- remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available
for AIX)
- incremental updates required to ppc directories due to platform specific changes
made in google repos while we complete the above steps.

With the update there are still some timeouts seen when run in simulated mode which
may be a result of the missing optimizations.  Once we have the optimizations in
we will review the simulation results and address/exclude tests as necessary so that
the simulated runs are clean.

Revert of Externalize deoptimization reasons. (patchset #7 id:120001 of https://codereview.chromium.org/874323003/)

Reason for revert:
This CL breaks RelocInfo::INTERNAL_REFERENCE (and maybe others that come after DEOPT_REASON), which is currently (mostly) unused on tip-of-tree, but will be used for jump tables soon(ish) and should therefore work. It seems to be a problem with implicitly assumptions about the number of reloc info modes. Needs further investigation.
