re PR target/51244 ([SH] Inefficient conditional branch and code around T bit)
PR target/51244
* config/sh/sh.md (negsi_cond, negdi_cond, stack_protect_test): Remove
get_t_reg_rtx when invoking gen_branch_true or gen_branch_false.
(*zero_extend<mode>si2_compact): Convert to insn_and_split. Convert
zero extensions of T bit stores to reg moves in splitter. Remove
obsolete unnamed peephole2 that caught zero extensions after negc T bit
stores.
(*branch_true_eq, *branch_false_ne): Delete.
(branch_true, branch_false): Convert insn to expander. Move actual
insn logic to...
(*cbranch_t): ...this new insn_and_split. Try to find preceding
redundant T bit stores and tests and combine them with the conditional
branch if possible in the splitter.
(movrt_xor, *movt_movrt): New insn_and_split.
* config/sh/predicates.md (cbranch_treg_value): New predicate.
* config/sh/sh-protos.h (sh_eval_treg_value): Forward declare...
* config/sh/sh.c (sh_eval_treg_value): ...this new function.
(expand_cbranchsi4, expand_cbranchdi4): Remove get_t_reg_rtx
when invoking gen_branch_true or gen_branch_false.
