Adds a blacklist of tests which are currently unsupported or broken in Ignition to
the mjsunit and test262 test status.
Also removes --ignition-script-filter flag, and adds a
--ignition_fallback_on_eval_and_catch flag which fallsback to fullcodegen for
functions which call eval or contain a catch block.

The current implementation of classes throws the TypeError at the wrong
point, after activating a new context when directly calling a class
constructor. According to the spec, the TypeError has to be thrown
in the caller context.

This removes special casing for the 'f.arguments' property accessor. Any
local 'arguments' variable should not be allowed to influence the value
returned by the indirect 'f.arguments' property. That property creates a
new object with a separate identity everytime it is read. This is by now
consistent with other browsers.

This fixes the representation type for values in JSArray::length fields
when JSNativeContextSpecialization lowers loads. Only arrays with fast
elements kind are guaranteed to have a Smi represented length.

The reason is when native_context_specialization flag is ture, X87 turbofan
will hit the known issue that X87 will change a sNaN to qNaN by default. And
then it will fail when bit-comparing the source (sNaN) and the result (qNaN).

Reason for revert:
because of merge mistake, "regress/" is missed when skipping one test case for X87.
"regress/" will be added when relanding it.

This makes sure that initializing assignments of let-declared variables
perform an environment lookup and hence keep the variable alive. This is
needed because full-codegen contains debug code verifying the variable
is still inside the TDZ at the initializing assignment.

This stages the general purpose inlining mechanism in TurboFan and
also disables the remaining tests that still fail. We do this to get
test coverage early and to avoid regressing inlining as we go along.

This introduces an explicit lazy bailout. It is wrapped in the call
node, mostly because the lazy deoptimization processing is married
to the call processing in the instruction selector and the code generator.
It is still a terrible hack.

The runtime flag in question makes no sense, because the feature cannot
be disabled without keeping the snapshot in sync. We should avoid having
the flag in our "mjsunit" test suite, so that CluserFuzz doesn't pick it
up. The test in question is already skipped, the change will not affect
test results on our waterfall.

Swarming won't support an incremental data file. By just
sorting the lowest hanging fruits to the beginning we
already get a big bang for the buck (>80% of the improvement
we get otherwise).
This will require semi-regular manual updates of the
slowest tests.

Whenever a generalization is computed, the inputs must be checked for being cleared, and if they are, the generalization must be Type::Any.
Hopefully this fixes Chromium issue 527994 as well.
