Instead, simply track it as a valid binding pattern. To do this in the case of
parenthesized formals, we delay throwing the binding pattern error for
parenthesized (and async "calls") until we know it's not an arrow function head
by itself.
This guarantees that if an arrow head is a valid binding pattern, it's either a
valid parenthesized head or a valid identifier, or invalid pattern ("array" or
"object" literal style). We can detect the latter case by checking that the
current token is not a RPAREN and the expression isn't an identifier.
(Alternatively we could check that the curren token is RBRACE or RBRACK...)

We recently changed embedded builtins to be emitted as raw assembly
files during the build process in order to support MSVC (which doesn't
support inline assembly on x64). Ninja uses ml.exe / ml64.exe as the
assembler on all Windows builds (msvc & clang); these unfortunately
don't support large data streams well and can take over 5 minutes for
embedded.S.
With this CL we work around this by going back to inlined assembly for
clang Windows builds.

Moves allocation of the WasmModuleObject for asm.js code out of SyncCompileTranslatedAsmJS
since that is called when we are compiling the native context independent SharedFunctionInfo
and the WasmModuleObject requires a native context. Instead save the members required to
create the object in the AsmWasmData and create it during module instantiation. Note:
since the Wasm module is an implementation detail for asm_wasm code and isn't exposed,
this doeesn't have semantic change for asm.js code.
As part of this change, the AsmWasmData is changed from a FixedArray to a dedicated
struct. Some logic is also moved from module-compiler to wasm-engine to make the
seperation between Wasm SyncCompile and AsmJS SyncCompile more clear.
