that arise.

Exposed to the extras as extrasExports (on the builtins object), on
which they can put things that should be accessible from C++. Exposed
to C++ through the V8 API as v8::Context::GetExtrasExportsObject().
Adding a test (in test-api.cc) required adding a simple extra,
test-extra.js, which we build into the standalone builds.

Currently only the Win64 bots report this warnings, which adds quite
some overhead to the development process. With this flag we also get
compiler warnings about implicit 64bit to 32bit truncations when
building with clang on Linux/x64 and Mac/x64.

Compiling v8 for X87 platform with clang compiler leads to some test case failure.
So we set the default compiler for X87 to GCC.

The value returned on AIX for platform.machine() is not the
best value to map the architecture from. Use platform.system
to determine if we are on AIX and if so set host_arch to
ppc64 as AIX 6.1 (the earliest supported) only provides a
64 bit kernel
AIX was reporting warning that offset may be used uninitialized

Reason for revert:
The CL caused two issues:
- a weird build issue on V8 mips builder
- d8 cannot be invoked via PATH, since then it doesn't find its external snapshot.
The 2nd issue might even be WAI, but this needs more consideration.

The _GLIBCXX_DEBUG macro is now set by default for Linux Debug builds
and can be disabled using the disable_glibcxx_debug=1 setting
(compatible with Chrome). This will help us catch problems earlier.

Contribution of PowerPC port (continuation of 422063005 and 817143002). This patch covers
the key changes needed to the common files needed to support AIX. Subsequent
patches will cover:
- changes to update the ppc directories so they are current with the changes
in the rest of the project.
- remaining AIX changes not resolved by 4.8 compiler
- individual optimizations for PPC
This is based off of the GitHub repository

All builders that used level 1 should meanwhile define
v8_enable_slow_dchecks, and so they can use level 2 without losing
coverage. Level 2, however, is considerably faster, so we want to use it
on those builders as well. The make optdebug setting is not affected by
this change.

This allows the setting to be overridable by embedders,
at the cost of forcing embedders that don't build v8
using standalone.gypi to add this setting to their build
config.
