[APX NDD] Support APX NDD for sbb insn
Similar to *add<dwi>3_doubleword, operands[1] may not equal to operands[0] so
extra move and earlyclobber are required.
gcc/ChangeLog:
* config/i386/i386.md (*sub<dwi>3_doubleword): Add new alternative for
NDD, adopt '&' modifier to NDD dest and emit move when operands[0] not
equal to operands[1].
(*sub<dwi>3_doubleword_zext): Likewise.
(*subv<dwi>4_doubleword): Likewise.
(*subv<dwi>4_doubleword_1): Likewise.
(*subv<mode>4_overflow_1): Add NDD alternatives and adjust output
templates.
(*subv<mode>4_overflow_2): Likewise.
(@sub<mode>3_carry): Likewise.
(*addsi3_carry_zext_0r): Likewise, and use nonimmediate_operand for
operands[1] to accept memory input for NDD alternative.
(*subsi3_carry_zext): Likewise.
(subborrow<mode>): Parse TARGET_APX_NDD to ix86_binary_operator_ok.
(subborrow<mode>_0): Likewise.
(*sub<mode>3_eq): Likewise.
(*sub<mode>3_ne): Likewise.
(*sub<mode>3_eq_1): Likewise.
gcc/testsuite/ChangeLog:
* gcc.target/i386/apx-ndd-sbb.c: New test.
