sparc.h (TARGET_CM_MEDMID): Fix documentation. 

* config/sparc/sparc.h (TARGET_CM_MEDMID): Fix documentation.
	(CASE_VECTOR_MODE): Set to SImode even if PTR64, when MEDLOW and
	not doing pic.
	(ASM_OUTPUT_ADDR_{VEC,DIFF}_ELT): Check CASE_VECTOR_MODE not
	Pmode.
	* config/sparc/sparc.md (tablejump): Likewise, and sign extend op0
	to Pmode if CASE_VECTOR_MODE is something else.
