clemensh be1a5f7551 [asm] Fix lots of invalid asm.js tests
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.
