re PR target/17862 (internal compiler error: in sparc_asm_function_prologue) 

PR target/17862
	* config/sparc/sparc.c (sparc_output_mi_thunk): Set
	current_function_uses_only_leaf_regs as well as sparc_leaf_function_p.

	* config/sparc/sparc.c (sparc_gimplify_va_arg): Pass 'false' instead
	of 0 as 4th argument to pass_by_reference.
	Call build_va_arg_indirect_ref instead of build_fold_indirect_ref.
