This is preparatory cleanup work for eventually tracking the functions
(rather than concrete closures) in the CALL_IC, also for builtins like
the default PromiseCapability [[Resolve]] and [[Reject]] functions. It
adds a new FeedbackCell type, which is used by JSFunctions consistently
now to reference the feedback vector (or undefined if not the function
is not compiled yet or is a native/asm.js function).
This also changes the calling convention for FastNewClosure builtin and
the JSCreateClosure operator in TurboFan to carry the FeedbackCell here
instead of the parent FeedbackVector and the slot index. In addition we
eliminate the now unused %InterpreterNewClosure runtime function.

We don't use parser caches anymore and request code caches
explicitly using ScriptCompiler::CreateCodeCache. Hence
removing the support for both parser cache and code cache options.
They are still retained in CompileOptions for backwards
compatibility. Apart from the api.cc, no other part should see
this option.

Before, configurations were chosen on clusterfuzz side. This migrates
the choice to the V8 repo, to enable easier changing it and to allow

This is a partial revert of:
https://crrev.com/c/890938 and https://crrev.com/c/893982
Before this CL, the test runner blocked on ongoing tests in order to
process their results after an internal timeout. However, the logic
required for this feature was overly complicated and prevented an
acceptable implementation for fast aborts. Furthermore, also the fuzzers
suffered from timeouts on swarming due to hanging tests.
Instead, we now abort immediately on internal timeout (used on
fuzzers), SIGINT (Ctrl-C) and SIGTERM. Ongoing tests are immediately
terminated and their results are disregarded. On SIGTERM and SIGINT,
we return with non-zero exit codes, and zero on internal timeout.
This will also properly return json output, when the external hard
timeout is reached on swarming (causes SIGTERM).

Timeouts on num-fuzzer only lead to false positives, as tests might
take unpredictably longer.
This CL forgives timeouts through a global override mechanism of the
expected outcomes. This allows to remove already existing scattered
code that allowed timeouts in some test suites only.
