VPR_REG is the only register in its class, so it should be handled by
TARGET_CLASS_LIKELY_SPILLED_P, which is achieved by calling
default_class_likely_spilled_p.  No test fails without this patch, but
it seems it should be implemented.

	* config/arm/arm.c (arm_class_likely_spilled_p): Handle VPR_REG.
