Fixed bug #74431

If the last instruction in a block is a NOP, then `new_opline`
here won't be a copy of `opline`, it will be a copy of the last
non-NOP opline. Avoid performing a spurious update by explicitly
checking for NOP.

Exception safety for direct CV assign of *CALL instrs

Converting T = *CALL; ASSIGN $v, T into $v = *CALL may not be
safe if an exception is thrown after the return value has been
populated -- in this case the value might be destroyed twice.

NOPs need to be tracked in the shiftlist as well, as there may be
jumps to NOPs.

Improve previous fix

Do not mark loop var free blocks as reachable after all -- as we
can't construct SSA for unreachable blocks, this would cause
issues down the line.

Instead add an extra UNREACHABLE_FREE flag and retain only the
FREE instruction during NOP removal. (If we retain all
instructions in the BB we might leave a jump instruction that goes
into the nowhere.)
