Don't disable hash randomization option in predictable mode.

We don't need it because
1) hash randomization uses random generator whose results depend on --random-seed option which is set in predictable mode.
2) disabling hash randomization triggers assert in snapshot mode.

A64: Move veneer emission checking in the Assembler.

The previous heuristic would break as a significant amount of code could be
generated without checking for veneer emission.
The veneer emission is now done in the Assembler, in a very similar way to
constant pool emission.
