[arm] Fix gcc.target/arm/xor-and.c
This test is naughty because it doesn't use the proper effective target checks
and add-options mechanisms for setting a Thumb1 target, which leads to Thumb1 hard-float errors
when testing a toolchain configured with --with-cpu=cortex-a15 --with-fpu=neon-vfpv4 --with-float=hard --with-mode=thumb.
This patch fixes that in the obvious way.
* gcc.target/arm/xor-and.c: Fix armv6 effective target checks
and options.
