Merge ProfileData into ProfileRuntime

Summary:
Collapsing the two singletons into one.  All profiling bookkeeping is now held
within the ProfileRuntime instance, with the exception of the LiveTypeMap.  Our
tests depend upon this structure having a global lifetime.

Notable behavior changes:

* All overloads of `serialize()` and `deserialize()` will now print the number
  of bytes, code objects, and types read/written.

* `RuntimeTest` no longer tears down the fixture after running and collecting a
  profile.  Doing so is a bit of a lie, we reset the JIT, but we can't actually
  reset the live types map because then we wouldn't be able to use the profile
  we saved (the string types don't have a mapping to anything).  So it's more
  natural to make the fixture run the code, generate profiling info, and then
  prepare to generate HIR without resetting the JIT metadata.
