commit r15-2661-gd80dcff99f3ca8721eecd82097281095a3122079

i386: Fix memory constraint for APX NF
The je constraint should be used for APX NDD ADD with register source
operand. The jM is for APX NDD patterns with immediate operand.
gcc/ChangeLog:
* config/i386/i386.md (nf_mem_constraint): Fixed the constraint
for the define_subst_attr.
(nf_mem_constraint): Added new define_subst_attr.
(*add<mode>_1<nf_name>): Fixed the constraint.
