Eliminate the beam_except pass
The beam_except pass rewrites certain calls `erlang:error/{1,2}` to
use specialized instructions for common exceptions such as
`{badmatch,Term}`.
Move this optimization to `beam_ssa_pre_codegen` and `beam_ssa_codegen`.
The main reason for this change is that optimization passes operating
on SSA code are easier to maintain than optimization passes working
on BEAM code.
