[spu, commit] Define TARGET_HAVE_SPECULATION_SAFE_VALUE

The SPU processor is not affected by speculation, so this macro can
safely be defined as speculation_safe_value_not_needed.

gcc/ChangeLog:

	PR target/86807
	* config/spu/spu.c (TARGET_HAVE_SPECULATION_SAFE_VALUE):
	Define to speculation_safe_value_not_needed.
