re PR rtl-optimization/47866 (gcc.dg/torture/vector-2.c fails on IA64) 

PR rtl-optimization/47866
	* expr.c (store_field): If MEM_SCALAR_P (target), don't use
	MEM_SET_IN_STRUCT_P (to_rtx, 1), just set MEM_IN_STRUCT_P (to_rtx)
	if target wasn't scalar.
	* function.c (assign_stack_temp_for_type): Assert that neither
	MEM_SCALAR_P nor MEM_IN_STRUCT_P is set previously, set either
	MEM_IN_STRUCT_P or MEM_SCALAR_P instead of using MEM_SET_IN_STRUCT_P
	macro.
	* rtl.h (MEM_SET_IN_STRUCT_P): Removed.
