xfail fp-uint64-convert-double-* on all arm targets
It wasn't long ago that I xfailed these tests on arm-*-eabi, but the
fail is expected on all other arm targets: even when hard float is
available, conversions between 64-bit integers and double are always
emulated on ARM, and the emulation disregards rounding modes. So,
bump the xfail to all of arm-*-*.
for gcc/testsuite/ChangeLog
* gcc.dg/torture/fp-uint64-convert-double-1.c: XFAIL on all of
arm-*-*.
* gcc.dg/torture/fp-uint64-convert-double-2.c: Likewise.
