in re_op_compile(), keep code_blocks for qr//

code_blocks is a temporary list of start/end indices and pointers to DO
blocks, that is used during the regexp compilation. Change it so that in
the qr// case, this structure is preserved (attached to regexp_internal),
so that in a forthcoming commit it will be available for use when
interpolating a qr within another pattern.
