beam_dead: Improve creation of select_val from is_eq_exact

When converting a comparison BIF (such as '=:=') to a test
instruction, run the other optimizations on the result.

When trying to combine is_eq_exact tests, handle the case
that is_eq_exact is followed by a jump instead of a label
to handle a test that has been newly converted from a BIF.

Taken together, those changes will coalesce more is_eq_exact
instructions into select_val instructions.
