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.
