re PR target/52375 (internal compiler error: in extract_insn, at recog.c:2123 at -O3 -mfpu=neon)
PR target/52375
* config/arm/neon.md (vashr<mode>3, vlshr<mode>3): Use
s_register_operand in the test instead of REG_P. Don't call
gen_reg_rtx if it won't be used.
* gcc.target/arm/pr52375.c: New test.
* gcc.c-torture/compile/pr52375.c: New test.
