Introduce expression::first_opcode
This adds a new helper method, expression::first_opcode, that extracts
the outermost opcode of an expression. This simplifies some patches
in the expression rewrite series.
Note that this patch requires the earlier patch to avoid manual
dissection of OP_TYPE operations.
