Smoke test for control flow with branchovers

It's frustratingly difficult to actually create control flow
translations from PHP.  Note that I tweaked the translation threshold
for this one.

Tidy up mc-generator.h

I was going to attempt to rationalize the interface between
MCGenerator and Translator, but I got as far as cleaning up the header
organization here and decided not to sink any more time into it.  I
think this looks nice, anyways.

Fixed a typo in Redis __call function

It seems like there is a typo in the Redis class. The code is reading the value from $func['defualts'] instead of $func['defaults'].

Merge AsyncESuspend+RetC and ContSuspend into AsyncSuspend

Converge eagerly executed and resumed parts of async functions further
and merge AsyncESuspend/ContSuspend opcodes into AsyncSuspend, which is
now responsible for suspending execution and returning control to the
caller (creating AsyncFunctionWaitHandle if executed eagerly).

The CreateCont opcode was modified correspondingly and RetC is no longer
needed.

Merge AsyncWrapResult+RetC and ContRetC into RetC

Make the behavior of RetC opcode context specific:

- standard return in normal function
- wrap into StaticResultWaitHandle in eagerly executed async function
- write result into the Continuation object in resumed async function
  and generator

The eager and resumed parts of the async function bodies are now exactly
same and ready for deduplication.

Use full-width LowPtr wrapper even without USE_LOWPTR

Doing so should help us avoid some obvious (pre-testing) bugs that might
come up because of build flag differences.  There is no perf impact.

Also updates the gdb pretty-printer to recognize LowPtr.
