re PR rtl-optimization/13260 (Incorrect optimisation of loop termination condition)
PR optimization/13260
* sh-protos.h (sh_expand_t_scc): Declare.
* sh.h (PREDICATE_CODES): Add cmpsi_operand.
* sh.c (cmpsi_operand, sh_expand_t_scc): New functions.
* sh.md (cmpsi): Use cmpsi_operand. If T_REG is compared to
something that is not a CONST_INT, copy it into a pseudo register.
(subc): Fix description of new T value.
(slt, sgt, sge, sgtu): Don't clobber T after rtl generation is over.
(sltu, sleu, sgeu): Likewise.
(seq, sne): Likewise. Use sh_expand_t_scc.
