Bytecode expectations have been moved to external (.golden) files,
one per test. Each test in the suite builds a representation of the
the compiled bytecode using BytecodeExpectationsPrinter. The output is
then compared to the golden file. If the comparision fails, a textual
diff can be used to identify the discrepancies.
Only the test snippets are left in the cc file, which also allows to
make it more compact and meaningful. Leaving the snippets in the cc
file was a deliberate choice to allow keeping the "truth" about the
tests in the cc file, which will rarely change, as opposed to golden
files.
Golden files can be generated and kept up to date using
generate-bytecode-expectations, which also means that the test suite
can be batch updated whenever the bytecode or golden format changes.
The golden format has been slightly amended (no more comments about
`void*`, add size of the bytecode array) following the consideration
made while converting the tests.
There is also a fix: BytecodeExpectationsPrinter::top_level_ was left
uninitialized, leading to undefined behaviour.

This is to enable deduplicating performance tests. We'll
create a hash of all relevant files and send it to perf bots
alongside the other swarming hashes (follow up on infra
side).
This will not actually run on swarming yet, but could at
some later point.
This splits off the cctest executable from other verification
test files, as those are not needed in performance tests.

Add gyp support and isolates for default test suites.
Add two default isolates, one (default) for using the
test suite collection we call "default" on the bots. One
(developer_default) for also supporting the way developers
call the driver (i.e. without argument, which includes
the unittests).
