vms.h (CASE_VECTOR_MODE): Define.

2012-03-27  Tristan Gingold  <gingold@adacore.com>

	* config/ia64/vms.h (CASE_VECTOR_MODE): Define.
	* config/ia64/ia64.md: Remove mode in template.
	Sign extend operand in expand_simple_binop.
	* config/ia64/ia64.h (ASM_OUTPUT_ADDR_DIFF_ELT): Use
	CASE_VECTOR_MODE instead of TARGET_ILP32.
	(ADDR_VEC_ALIGN): Make it depends on CASE_VECTOR_MODE.
