We incorrectly disallowed eval and arguments in accessor and method
names. This was because we checked the name inside the
ParseFunctionLiteral. We now flag accessors so that lazy parsing of
these functions are treated correctly.

This adds an "experimental" API hook (v8::ScriptCompiler::CompileModule)
allowing compilation of modules. The code gen is incredibly basic: the
module body is represented by a Block in the AST. But this at least gets
more of the pipeline working, and opens the door to writing mjsunit tests
(once d8 is modified to support module compilation).

Previously it just had hacks to have NULLs instead of them and pretended to know
nothing about Zone. The hacks provide no real benefit (probably historically
based on some weird misconception about the relationship between Zone and
Isolate), and make it harder for the PreParser to start to know more about
variables and scoping.

Contribution of PowerPC port (continuation of 422063005, 817143002 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.

1) The hardcoded strings were converted into DeoptReason enum.
2) Deopt comment were converted into a pair location and deopt reason entries so
the deopt reason tracking mode would less affect the size of the RelocInfo table and heap.
3) DeoptReason entry in RelocInfo reuses kCommentTag value and generates short entry in RelocInfo table.

It doesn't do anything for now, but it implies strict mode. Added tests to

Make sure the initial graph is fully populated with source position information and automatically propagate that information down through newly allocated nodes during reduction passes in the most unobtrusive way that's currently possible.

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.
