Blink already has code for handling invalid cached data. The attached test
ensures that cached data is gracefully rejected if it cannot be used.
This also unifies parser cache and code cache handling.

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.)

If we hade }` the right brace was always treated as part of the

the literal when we continue to parse the template literal after a

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.

Instead, make it possible for indifidual tests to pass "always true flags" which
are not part of the varying flag set.
The downside is that if an experimental flag changes parsing of some of the
unrelated code snippets, it's noticed later (only after the flag is turned on by
default). But this is a reasonable trade off for faster tests.
Additional fix: Some tests (ErrorsFutureStrictReservedWords) were using
always_flags incorrectly (running two different tests with different
always_flags basically iterates over every flag combination anyway - most of
them twice).

Most of the run time came from testing with all possible flag combinations. None
of the flags passed affect the test, and there are specialized tests for testing
the features behind the flags; no need to slow down the generic test.
With these changes, run time for debug build goes from 186 s to 0.5 s.
In addition, fixed some missing commas between the test cases.
