The CommonOperatorReducer currently takes care of redundant Phis,
EffectPhis and Selects. This functionality overlaps with ControlReducer,
but is required to make certain optimizations effective, since the
ControlReducer only runs really early and really late in the pipeline
and therefore other reducers aren't reapplied properly after redundant
phi/select elimination.

Convert all results to floats and log errors on failing
conversions. Otherwise these results bubble up into
buildbot.

This is an initial version of redundant load elimination, currently
limited to LoadField operators, and implemented by walking the effect
chain.

These methods for used for compressed libraries, where GetSource* functions
contained the compressed sources and [GS]etRawSource* the uncompressed
sources. This is dead code since the API no longer supports compression.
(If you need/want compressed sources, use the external startup data and
compress/uncompress on the Embedder's side.)

This adds a common perf configuration for JSTests including
Classes, Collections, Iterators and Strings. This allows
the android test runner to handle subdirectories correctly
and to share the base.js resource in the parent directory.
The new json config has added resources configs for the
Android runner.
The perf runner's relative paths on the device are fixed as
well. Resources are only pushed on the configuration node
where they are specified. They are pushed to a dir on the
device that follows the same directory structure as on the
host. The binary is executed in the benchmark folder on the
device like on the host to allow relative path file
loading.

This is basically a refactoring that extracts desktop
specific code into a separate class.
Also adds flags for android runs (not used yet).

This switches off the resources feature. It will be solely
used for configuring files to be copied to android devices
in a follow up CL.

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.

There are separated JS and C stacks on simulators so for some stack
extensive tests (like mozilla/js1_5/extensions/regress-355497) might
cause a C stack overflow and that overflow is not caught by V8. It is
not an issue on real HW. Increasing the C stack also solves the problem
but we have already FLAG_sim_stack_size flag to control the JS stack
size.
This patch makes it possible to add flags to tests conditionally in
.status files.
