[APX EGPR] Add register and memory constraints that disallow EGPR
For APX, as we extended the GENERAL_REG_CLASS, new constraints are
needed to restrict insns that cannot adopt EGPR either in its reg or
memory operands. We added a series of constraints for general/backend
ones that related to GPR usage. All of them are prefixed with "j" to
indicate the constraints does not allow EGPR.
gcc/ChangeLog:
* config/i386/constraints.md (jr): New register constraint
that prohibits EGPR.
(jR): Constraint that force usage of EGPR.
(jm): New memory constraint that prohibits EGPR.
(ja): Likewise for Bm constraint.
(jb): Likewise for Tv constraint.
(j<): New auto-dec memory constraint that prohibits EGPR.
(j>): Likewise for ">" constraint.
(jo): Likewise for "o" constraint.
(jv): Likewise for "V" constraint.
(jp): Likewise for "p" constraint.
* config/i386/i386.h (enum reg_class): Add new reg class
GENERAL_GPR16.
