The MIPS16 port has never handled long branches properly; see PR 51931
for the details. It isn't easy to xfail MIPS16-specific problems at
the dejagnu level because of -mflip-mips16, so the patch below forces
a nomips16 attribute instead.
Tested on mips64-linux-gnu and applied.

* gcc.c-torture/compile/20001226-1.c: Add nomips16 attribute.
* g++.dg/opt/longbranch1.C: Likewise.
