Only FullCodegen code ever gets flushed by code flushing. Since we are
deprecating the old pipeline, the added complexity introduced by code
flushing is no longer worth it. This CL removes it (but keeps code aging,
which is used to unlink SFIs from the compilation cache).

The current test/fuzzer/wasm directory is used for two things:
1) as the corpus directory for clusterfuzz
2) to test in v8 that the fuzzer runs correctly.
With the newly added files from the wasm spec tests this directory grew
quite big and adds unnecessary load on the trybots. Therefore I want to
do the following steps:
1) In this CL for V8: create a new directory for the clusterfuzz corpus
2) In chromium: use the new corpus directory
3) In v8: clean up the old directory to use it on the trybots.

1. Replaces --crankshaft with --opt in tests.
2. Also fixes presubmit to check for --opt flag when
assertOptimized is used.
3. Updates testrunner/local/variants.py and
v8_foozie.py to use --opt flag.
This would mean, nooptimize variant means there are
no optimizations. Not even with %OptimizeFunctionOnNextCall.

The spec tests are stored on a mirror and are downloaded with the DEPS
file. The test files on the mirror are updated with a script which has
to be executed manually.
This CL contains the following changes:
* A script which updates the spec tests and uploads the generated files
to the mirror.
* Changes to the DEPS file to download the files from the mirror.
* Changes so that tools/run-tests.py can run the spec tests.

Traditionally, we had a prefix for a function name of "~" for
unoptimized code and "*" for optimized code. Restore this prefix
in v8/tools/ic-processor. It's really cool to know if an IC was
called from optimized code (often a hint of poor performance!).
