358378c1c0 LibRegex: Pick the right target for OpCode_Repeat 
Repeat's 'offset' field is a bit odd in that it is treated as a negative
offset, causing a backwards jump when positive; the optimizer didn't
correctly model this behaviour, which caused crashes and misopts when
dealing with Repeats.
This commit fixes that behaviour.

4a8d3e35a3 LibRegex: Add some more debugging info to bytecode block ranges 
These were getting difficult to differentiate, now they each get a
comment on where they came from to aid with future debugging.

00bc22c332 LibRegex: Don't immediately ignore TempInverse in optimizer 
fe46b2c141 added the reset-temp-inverse flag, but set it up so all
tempinverse ops were negated at the start of the next op; this commit
makes it so these flags actually persist for one op and not zero.

Fixes #2296.
