[testsuite] fix gcc.target/powerpc/sd-vsx.c and sd-pwr6.c

[Janis Johnson]

Tests gcc.target/powerpc/sd-vsx.c and sd-pwr6.c assume that decimal
floating point is supported on the target, but this is not true for
powerpc-none-eabi.  This obvious patch skips the test if dfp is
not supported; checked in for mainline.

	* gcc.target/powerpc/sd-vsx.c: Require dfp.
	* gcc.target/powerpc/sd-pwr6.c: Likewise.
