Updated toolchain.gypi to support v8 using CLANG on MIPS. These changes
include using integrated assembler with CLANG, and disabling options
used by GCC which are not supported by CLANG.
Reland https://codereview.chromium.org/1519493002 with fix to remove
duplicated 'conditions' sections.

v8 is optimized for speed. Because GCC LTO merges flags at link time,
we disable LTO to prevent any -O2 flags from taking precedence over v8's
-Os flag. However, LLVM LTO does not work this way so we keep LTO enabled
under LLVM.
This fixes the ARM build in the cfi_vptr==1 configuration, which requires
LLVM LTO.

Remove references to android_webview_build now that we no longer support
that build configuration. This also removes use_system_stlport which was
only supported with android_webview_build.

We were able to remove most of our changes needed to compile
on AIX with an earlier compiler level. These changes are the
remaining ones.
The changes in heap/heap.cc are needed because otherwise the
compiler complains that result is potentially used before
it is initialized.
The changes in heap/mark-compact.cc are required because
AIX supports the full 64 bit address range so the check
being guarded is invalid.
The changes in build/toolchain.gypi and
test/cctest/cctest/gyp are aix only and are adjust the
compile/link options to allow the AIX build to succeed.

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.

Mostly copy and paste from Chromium with customization for
V8 where necessary.

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

This way we stay in sync with what Chromium does and we reduce the
number of bugs caused by 80-to-{32,64}-bit rounding errors. It's also
a requirement for switching to signaling NaN for FixedDoubleArray holes.

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.

The current gyp config tries to test whether the compiler is an arm / mips
compiler and whether it supports -m32 / -m64 based on a test within gyp.
Unfortunately CXX / CXX_target / CXX_host are no no longer set early enough
in gyp for this to work, and so all of these tests were actually being done
using "$(which g++)" rather than the appropriate CXX_target / CXX_host compiler.
This change removes these dynamic tests and instead bases the decisions on
knowledge of the host / target / v8_target architecture combination. The
the -m32/-m64 flags are set based on host_cxx_is_biarch / target_cxx_is_biarch,
which are set to reasonable defaults of only ia32/x64 or clang compilers
being build for biarch support. The host_cxx_is_biarch / target_cxx_is_biarch
variables can be overriden if required.

Simplify the compile time feature detection on Arm:
- Define CAN_USE_XXX definitions unconditionally for all target/host
toolchain combinations
- Rename arm_test / ARM_TEST to arm_test_noprob / ARM_TEST_NO_FEATURE_PROBE
- Don't set ARM_TEST_NO_FEATURE_PROBE implicitly on the simulator to make
make simulator / native more consistent
- Unify CpuFeatures::PrintTarget for simulator and native builds
- Remove unecessary CAN_USE_VFP_INSTRUCTIONS definition for android (this is
the default for arm_fpu=default)
- Add a CpuFeatures::Probe() before calling CpuFeatures::PrintFeatures() in PrintHelp
to ensure we have probed features before printing them.
