re PR target/54089 ([SH] Refactor shift patterns)
PR target/54089
* config/sh/sh.h (SH_DYNAMIC_SHIFT_COST): Set always to 1 if
dynamic shifts are available.
(SHIFT_COUNT_TRUNCATED): Always define to 0. Correct comment.
* config/sh/sh.c (ashl_lshr_seq, ext_ashl_lshr_seq): Add comments.
* config/sh/predicates.md (shift_count_operand): Allow
arith_reg_operand even if TARGET_DYNSHIFT is false.
* config/sh/sh.md (ashlsi3, lshrsi3): Expand library call patterns
if needed.
(ashlsi3_d_call, lshrsi3_d_call): New insns.
PR target/54089
* config/sh/lib1funcs.S (ashlsi3): Reimplement as ashlsi3_r0.
(lshrsi3): Reimplement as lshrsi3_r0.
