Log message:

	Fix SHcompact exception handling:
	* sh.c (sh_get_pr_initial_val): If PR is or miight be clobbered
	by the prologue, return a MEM with return_address_pointer_rtx
	as address.
	* sh.h (HARD_REGNO_MODE_OK): PR is OK for SImode.
	(RETURN_ADDR_OFFSET): Don't define.
	(SH_DBX_REGISTER_NUMBER): Use SHmedia numbers for SHmedia
	registers that are visible in compact mode.  Show that SHmedia
	registers still exist in compact mode, even if there are not
	readily accessible.
	(ASM_PREFERRED_EH_DATA_FORMAT): Supply DW_EH_PE_indirect
	if GLOBAL.  Use DW_EH_PE_textrel (nominally) for CODE,
	and DW_EH_PE_pcrel for pic data.
	(ASM_MAYBE_OUTPUT_ENCODED_ADDR_RTX): If DW_EH_PE_textrel,
	set SYMBOL_FLAG_FUNCTION in symbol, and actually use
	DW_EH_PE_pcrel / DW_EH_PE_absptr encoding.
	(ALLOCATE_INITIAL_VALUE): Put PR on stack if prologue clobbers it.
	* sh.md (movsi_media-1): New splitter.
