[APX] Prohibit SHA/KEYLOCKER usage of EGPR when APX enabled
The latest APX spec announced removal of SHA/KEYLOCKER evex promotion,
which means the SHA/KEYLOCKER insn does not support EGPR when APX
enabled. Update the corresponding constraints to their EGPR-disabled
counterparts.
gcc/ChangeLog:
* config/i386/sse.md (sha1msg1): Use "ja" instead of "Bm" for
memory constraint.
(sha1msg2): Likewise.
(sha1nexte): Likewise.
(sha1rnds4): Likewise.
(sha256msg1): Likewise.
(sha256msg2): Likewise.
(sha256rnds2): Likewise.
(aes<aesklvariant>u8): Use "jm" instead of "m" for memory
constraint.
(*aes<aeswideklvariant>u8): Likewise.
(*encodekey128u32): Use "jr" instead of "r" for register
constraints.
(*encodekey256u32): Likewise.
