bradnelson 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.
