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 essentially performs the following transformation
JSToNumber(phi(x1,...,xn,control):primitive)
=> phi(JSToNumber(x1),...,JSToNumber(xn),control):number
which is similar to what we already do for JSToBoolean.
