Fix false LocalJumpError when branch coverage is enabled
`throw TAG_BREAK` instruction makes a jump only if the continuation of
catch of TAG_BREAK exactly matches the instruction immediately following
the "send" instruction that is currently being executed. Otherwise, it
seems to determine break from proc-closure.
Branch coverage may insert some recording instructions after "send"
instruction, which broke the conditions for TAG_BREAK to work properly.
This change forces to set the continuation of catch of TAG_BREAK
immediately after "send" (or "invokesuper") instruction.
