Change OP_MATCHERR from Z format (unconditional) to B format
(conditional on register). This allows fusing JMPIF + MATCHERR
sequence into a single MATCHERR instruction for simple patterns.

Before: JMPIF R2 target (4 bytes) + MATCHERR (1 byte) = 5 bytes
After:  MATCHERR R2 (2 bytes)

Saves 3 bytes per pattern match with raise_on_fail.
