simplify OP_COMPUTEDGOTO with unique and known target
If the OP_COMPUTEDGOTO's source pseudo is defined by a single
OP_SETVAL/EXPR_LABEL, then the corresponding basic block is the
only possible destination and the computed goto can then be
simplified into a simple branch.
So, convert such computed goto into a simple OP_BR which may
then participate in other flow simplifications.
