Allows for getting rid of the special casing for float64 and is probably
faster.

...when handing out validity cells to handlers; because invalidating said cells is
the only time we'll need the user registrations.
Along the way, fix a corner case in WeakFixedArray, which can now be empty after
the recently introduced compaction support.
This reverts commit 968715c653.

This fixes a race where
- mutator changes the fixed array length by trimming it,
- sweeper thread reads the length of the fixed array.
Also rename FROM_GC and FROM_MUTATOR to be more precise.

Calling new Array(JSObject::kInitialMaxFastElementArray) in optimized code
makes a stub call that bails out due to the length. Currently, the bailout
code a) doesn't have the allocation site, and b) wouldn't use it if it did
because the length is perceived to be too high.
This CL passes the allocation site to the stub call (rather than undefined),
and alters the bailout code to utilize the feedback.
