Similar to LSHIFT, rshift do not need to omit $1 for NDD form.
gcc/ChangeLog:
* config/i386/i386.md (ashr<mode>3_cvt): Extend with new
alternatives to support NDD, and adjust output templates.
(*ashr<mode>3_1): Likewise for SI/DI mode.
(*lshr<mode>3_1): Likewise.
(*<insn>si3_1_zext): Likewise.
(*ashr<mode>3_1): Likewise for QI/HI mode.
(*lshrqi3_1): Likewise.
(*lshrhi3_1): Likewise.
(<insn><mode>3_cmp): Likewise.
(*<insn><mode>3_cconly): Likewise.
(*ashrsi3_cvt_zext): Likewise, and use nonimmediate_operand for
operands[1] to accept memory input for NDD alternative.
(*highpartdisi2): Likewise.
(*<insn>si3_cmp_zext): Likewise.
(<insn><mode>3_carry): Likewise.
gcc/testsuite/ChangeLog:
* gcc.target/i386/apx-ndd.c: Add l/ashiftrt tests.
