Hi,
  While working on an aarch64 patch, I ran into wrong code produced by
my patch.  I am not ready to submit the patch yet but since I reduced
the testcase and there was no testcase in the testsuite yet, I thought
I commit the testcase.  This testcase is reduced from
aarch64_float_const_representable_p in aarch64.c.

Thanks,
Andrew Pinski

ChangeLog:
* gcc.c-torture/execute/20141125-1.c: New testcase.
