The file snapshot_blob_host.bin was supposed to be generated when building the host toolset. However, the file snapshot_blob.bin was being generated instead, under every set of conditions.
...
Because of this, every time we build the host toolset, snapshot_blob_host.bin is not found. This causes the target (v8_external_snapshot) that generates such file to be run. This target generates snapshot_blob.bin instead of snapshot_blob_host.bin. This in turn causes all the targets that depend on snapshot_blob.bin to run again.
After this, we still don't have snapshot_blob_host.bin. So the next time we build, the whole process described above happens again.

Implement graph trimming in ControlReducer.

Trimming the graph consists of breaking links from nodes that are not reachable from end to nodes that are reachable from end. Such dead nodes show up in the use lists of the live nodes and though mostly harmless, just clutter up the graph. They also can limit instruction selection opportunities, so it is good to get rid of them.
This CL is one half of the ControlReducer functionality, the other half
being branch folding.

ECMAScript source text is a sequence of code points. All Unicode code

Refactoring InterfaceDescriptors away from code-stubs.h
...
Clean up and create seperation between the concept of a call descriptor and a

but the latter has many extra hints related to code generation and
deoptimization for the implementation of a particular code stub.

Summary:
- Changes in common code are mainly boilerplate changes,
gyp and test status files updates.
- On mips64 simulator all tests pass from all test units.
- Current issues: mjsunit JS debugger tests fail randomly on HW in release mode.
Corresponding tests are skipped on HW.
- Skipped tests on mips64: test-heap/ReleaseOverReservedPages, mjsunit/debug-*

This adds timestamps to allow profiling with code space reuse. Also a couple of updates to reflect the changes in the JIT perf interface + a move of the perf-related stuff into separate files.
Unfortunately, the change only works with the latest patch to the perf tool from a Linux perf tool contributor (Stephane Eranian).

[Re-retry of r21696 and r21739]
If the embedder chooses, the 'natives' (library sources) and the
precompiled startup blob can be written to files during the build
process and handed over to V8 at startup. The main purpose would be
to reduce the size of the compiled binary for space constrained
platforms.
The build-time option is off by default. Nothing should change if
it's not enabled.

[Arm]: Simplify compile-time Arm feature detection.
...
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.
