[wasm] [asm.js] Fix various asm.js issues.
...
Several of the asm.js tests were disabled and wrong (mismatched number of args
on the stdlib functions).
Fixing issue around negation and float + doubles.
Renaming function for IsNegate to IsInvert (to reflect what it actually does).
Added tests for negate and invert.

[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.
