Fix 64b-x-32b cross compiler breakage. Make alpha-x-m32r work again.

	* emit-rtl.c (operand_subword): Sign extend REAL_VALUE_TO_TARGET_SINGLE
	result.
	* final.c (split_double): Sign extend REAL_VALUE_TO_TARGET_DOUBLE
	result.
	* real.c (endian): Delete sign extension code.
	* config/m32r/m32r.md (movsf_insn+1): REAL_VALUE_TO_TARGET_SINGLE call
	replaced with operand_subword call.
