For vec_concatv2di, m constraint in alternative 0 and 1 could result in
egpr allocated on operand 2 under -mapxf. Should use jm instead.
Bootstrapped/regtested on x86-64-linux-gnu.
Ok for trunk?
gcc/ChangeLog:
* config/i386/sse.md (vec_concatv2di): Replace constraint "m"
with "jm" for alternative 0 and 1 of operand 2.
