Performed manual testing as well by making 20 CPU profile recordings of loading http://meduza.io page. Without the patch the page renderer memory size grows beyond 300MB.

For instance, it now knows that Number(x) has type Number. (In this particular case, we used to know that already due to js-call-reduction of Number but that was recently disabled because of BigInts.)

Control Flow Integrity [1] indirect call checking is a compiler- instrumentation that verifies that function pointers are only used to call functions whose type signatures matches the type of the function pointer. The once implementation casts function pointers to different types--refactor it to pass around a std::function that calls the provided function pointer with its original type instead.

The value is passed as int in most places anyway, so better also store it as int, and make sure that it's in the range [0..kMaxInt]. Also, our style guide only allows {int} out of the standard integer types.

For "top digit" (of the result) comparison to be applicable, we must also check that there are no further digits in the source. The included regression test flushes out another bug in "TruncateToNBits", so that gets fixed here too (in contrast to the first landing attempt). This reverts commit cb9e7af4.
