As mentioned in http://gcc.gnu.org/ml/gcc-patches/2013-11/msg02228.html, this
implements the trap pattern according to what was decided which brk should be
used.
OK? Built and tested on aarch64-elf with no regressions. Also built a glibc
for aarch64-linux-gnu with this patch included (LP64).
Thanks,
Andrew Pinski
* config/aarch64/aarch64.md (trap): New pattern.
