75128636f3 [wasm] Remove obsolete %IsNotAsmWasmCode predicate.
By now the predicate in question is an exact negation of %IsAsmWasmCode
as the name intuitively implies. The need for two separate test methods
no longer exists and one of the two can be removed.

e5f5ac7d2b [wasm] asm.js - Remove Wasm.instantiateModuleFromAsm, use asm.js directly.
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.

c5856779eb [wasm] Forbid sign mismatch in asm typer.
asm.js forbids mixing signed and unsigned % or /.
We had been allowing these.

Fixes crash.
