I identified lots of asm.js tests that are actually not valid according
to the spec, hence they execute in default-javascript-mode.
This CL fixes most of them by adding additional type annotations.
The atomic tests are totally non-spec-compliant by expecting a fourth
argument, and infinite-loops-taken expects a function-type parameter,
so I did not fix those.
I also did not fix the regression tests.

This allows us to remove the troublesome %_MathClz32 intrinsic and also
allows us to utilize the functionality that is already available in
TurboFan. Also introduce a proper NumberClz32 operator so we don't need
to introduce a machine operator at the JS level.

This test will fail once we optimize top-level code, because the
aforementioned intrinsic doesn't perform a NumberToUint32 conversion.
