This adds handling of simplified ops without effect input to the escape

22606f0c29 Enable component builds for fuzzers
V8 is collecting a growing amount of fuzzers, all of which take substantial
space on the bots and in chromium build archives. This CL improves that
situation by allowing component (shared library) builds for almost all fuzzers.

The parser fuzzer is handled as an exception since it would require exporting a
large number of additional functions.

A component build results in about a 50-100x improvement in file size for each
fuzzer (~50M-100M to around 1.1M).

13b8a1238b Move async/await JS support code out of experimental natives
The file formerly known as src/js/harmony-async-await.js does not
expose anything directly to JavaScript code; it just makes a few
functions available on the native context for the parser desugaring
to expand into. Experimental natives have various issues with
larger amounts of code, so this patch moves the JS builtins to
support async functions out of experimental natives and into the
core snapshot. The change would be done eventually anyway, but this
patch does it before removing the flag to support shipping the
feature while avoiding the pitfalls of experimental natives.

Drive by cleanup: remove more unused functions from the whitelist for experimental natives.

cd049c2c76 Fix crash from turning on DevTools in the middle of catch prediction
If DevTools is turned on in the middle of doing some things with async
functions, then more items may be popped from the Promise stack than were
pushed to it. In this sort of case, it's OK to have a catch misprediction,
but a crash is unacceptable. This patch defensively handles this edge
case where the Promise stack is unexpectedly empty for that reason.

29f1475a8d Refine duplicate arrow function parameter location handling
This patch fixes the logic of finding the location of a duplicate
parameter error in arrow functions by only looking at the error if it
exists. This should address a TSAN error. Further, an UNREACHABLE()
statement is inserted somewhere in the ExpressionClassifier code
to make future similar bugs easier to find.

f296dad962 Improve stack traces for async functions
This patch tracks the stack of async functions differently from other
Promise async stack tracking. With this patch, the stack trace of a
callstack of async functions should look similarly to the call stack
if all of the functions were synchronous. An example can be found in
the updated test expectations: https://codereview.chromium.org/2362923002 .

The new stack traces are implemented using existing mechanisms in the
inspector. The inspector has two ways to save async stack traces: recurring
and non-recurring stacks. An example of a non-recurring stack is setTimeout,
and a recurring one is saved for setInterval. Recurring stacks are deleted
only when a special "cancel" function is called, rather than being deleted
after being used the first time. Previous Promise async stack tracking always
used non-recurring stacks.

For async functions, this patch saves a recurring stack. The top frame of
the stack is duplicated, as the resuming function contains a similar frame;
the devtools frontend is responsible for removing or marking this frame,
which it can do based on seeing the [async function] line which follows it.
The second frame will instead be provided by the resuming execution
context. The recurring stack is saved when the async function is entered, and
it is deleted from a finally block. The id of the stack is saved in the outer
Promise being constructed by the async function. When an intermediate
throwaway Promise will be triggered as a reaction, it will be identified as
such based on its debugging metadata, and the corresponding async function's
recurring stack will be used.

3200fafa5f [interpreter] Compute and use type info percentage
Previously we would not have a total count of ICs when interpreting and
thus the check for sufficient type info would always succeed.
Also use the optimization checks for OSR while waiting for baseline
compilation and refactor the check.

73518a9070 [arm] Clean up use of IsSupported and IsEnabled.
CpuFeatures::IsSupported(feature) indicates that the feature is
available on the target. AssemblerBase::IsEnabled(feature) indicates
that we've checked for support (using CpuFeatureScope). The main benefit
is that we can test on (for example) ARMv8, but have some assurance that
we won't generate ARMv8 instructions on ARMv7 targets.

This patch simply cleans up the usage, which had become inconsistent.
The instruction emission functions now check not only that their
dependent features are supported, but also that we've verified that
using CpuFeatureScope.

83207f4853 Fix test-parsing/InnerAssignment.
It looks like it tried to trigger lazy inner function parsing by
inserting a comment into an inner function.

1) We don't have lazy inner functions yet.
2) Even if we had, there's no way this heuristic could trigger laziness:
we need to do the laziness decision upfront, without looking at the
contents / size of the function.
3) Some of the combinations were weird: lazy_outer but non-lazy inner?

In the current heuristics, only the total script size affects laziness;
in particular, it doesn't matter where the long comment is.

49695346ae [ic][ia32][x87] Don't push/pop value/slot/vector in store handlers.
According to new store IC calling convention the value, slot and vector are passed
on the stack and there's no need in trying to preserve values or respective registers
in store handlers.

Nice bonus: we also don't need virtual registers anymore.
