Fix a few items broken during review of scanner + parser:
* Make the scanner retain stale newline state on a rewind (as otherwise it must be able to correctly rewind that too, though it doesn't need it). (Probably should revisit).
* Change StashCode in the builder skip to the zero case, as it crashes for some reason (added TODO).
Also fix:
* Drop test based on constant expression evaluation in main parser
* Support constant defined based on existing constant.
* Type constants as signed.
* Added a check that all used functions are defined eventually.
* Zone allocate strings for simplicity (TODOs to refactor better).

This adds a --stress-validate-asm flag intended to stress test the
validator by running against every single function, independent of
whether a "use asm" directive is present. It mainly tests negative
cases because barely any function in our test corpus will be a valid
module according to the asm.js spec.

The function "foo" in "base_getter_test" was picking up a left-over
optimised code object from foo's code map, the third time that
base_getter_test was run, instead of optimising it itself. This
broke the assumptions of the test, that each case was functionally
independent from the others, and had started off with empty feedback
and no optimised code.
This breaks the test though, so we have to blacklist it pending a fix
to the root cause (http://crbug.com/v8/6101).

Mark slow tests discovered by manual audit of reported durations.
Slow tests will run first, which will lead to higher test runner throughput.
Also some tests have flaky timeouts occasionally.

This fixes various allocator methods to properly propagate {nullptr} to
callers without accidentally dereferencing it. We also disable one test
case for stress mode as it runs out of memory due to inlining limits
being lifted in the stress mode.

qNaN and sNaN values have different binary representation on MIPS
compared to ARM/x86 architectures. We are skipping these tests because
we can't provide specific NaNs encodings from ARM/x86 architectures.

Some tests require a lot of memory and they fail on buildbots if they run
in parallel with other tests of the same kind.
We try to limit this by disabling multiple vairants of the same tests,
assuming this would stop the failures in most of the cases.

Our test infrastructure ignores missing tests which are listed in
status files. Sometimes, tests are removed and status file lines
are not updated. This patch adds a presubmit check for status
files addressing JavaScript tests to not reference missing tests.
It also cleans up existing violations.

mjsunit/big-object-literal will exhaust the stack in debug builds,
due to different compiler settings. It will work in optdebug.
This disables for both. Adding an 'optdebug' test to .status files
is easy, but I don't want to contribute to the 'mode x variant explosion'.

This test requires its objects to live in new space, so running it
through gc stress runs just makes it susceptible to flakiness, as
was recently seen when turning on the --harmony-string-padding
flag (which just adds an extra JS file to the bootstrapper sequence).
