Make use of %IsAsmWasmCode in place of Wasm.instantiateModuleFromAsm,
in order to reduce the surface area of the Wasm object,
and to focus on testing asm.js coming in via the parser.
Ignore extra CONST_LEGACY assignment introduced by the parser
when modules have the form:
(function Foo(a, b, c) {..});
This requires both a validator and AsmWasmBuilder change.
Move stdlib use collection to import time,
to reject modules that import a function, even if not used.

This flag was shipped on in 52, so it's due for removal. The patch includes
removing the deprecated and unused-in-Blink API Promise::Chain, and many

The following code was previously accepted:
async function f() {
let g = (await) => {};
}
But per the spec, using 'await' is disallowed in arrow parameters
by an early error rule (just as 'yield' is disallowed in arrow
params inside generators).
There was special logic in ParseUnaryExpression which seems to have been
there only to allow that case. Having removed it, we get a SyntaxError in
the right cases anyway when ParseUnaryExpression chokes on whatever
illegal token follows 'await' in the cases this code previously handled.
Also removes the unnecessary AsyncBindingPatternProduction enum value.

When doing a component build, some test binaries link against the object
files directly, bypassing the components. This results, however, and
rightly so, in linker warnings. In gyp, we just suppressed them. During
the transition to gn, this was dropped for two binaries.
Here I add the suppressions back in.
Long term, we should either change the tests to go through the public
API, or export the required symbols.

Adds InterpreterCompilationJob as a sub-class of
CompilationJob, to enable off-thread bytecode
generation. Currently only used in
Interpreter::MakeBytecode.
As part of this change, CompilationJob is modified
to make it less specific to optimized compilation,
renaming the phases as follows:
- CreateGraph -> PrepareJob
- OptimizeGraph -> ExecuteJob
- GenerateCode -> FinalizeJob
RegisterWeakObjectsInOptimizedCode is also moved out
of CompilationJob and instead becomes a static function
on Compiler.

This patch subsumes CoverInitializedNameProduction to create an ObjectLiteralProduction which is now used to report the duplicate proto error as well.
This patch also changes ObjectLiteralChecker::CheckProperty

bailing out immediately. Once we realize that we're in a

As required by the spec, ToJS now throws a TypeError fit I64 values
instead of truncating the I64 value to I32. To throw a TypeError I
introduced a new runtime function because the existing
Runtime::kThrowWasmError does not throw a TypeError. Since we have calls
to two runtime functions now, and an additional one is needed for stack
checks, I extracted the call to runtime functions into a helper function.
