Optimise "CB 1:SHL" to "DUP:ADD"

This saves one byte and by my count is about 11 cycles faster.

Check type in emit_dab and emit_daw

Expose longer sequences to the optimiser
...
emit_seq() no longer emits directly but adds the sequence to a pending
sequence, which we emit only when necessary (e.g. when we're about to
emit a branch target, or when the parser is about to emit an opcode
directly).
This exposes more opportunities to the optimiser - in particular, the
earlier commit which taught the optimiser how to change things like
"SLW [n]:LLW [n]" to "DLW [n]" now gets a chance to kick in where one
statement updates a variable and the following statement uses the
updated value.

Refactor elimination of *current* op in optimiser
...
The code to handle this was duplicated in two places; this pulls it out
to a common chunk of code triggered by negative values of freeops.
This isn't a big win here, but it sets us up to re-use this code in
later commits.
