	* expr.c (push_value): Only call flush_quick_stack for non-constant
	arguments.
	(build_java_throw_out_of_bounds_exception): No longer wrap calls
	to _Jv_ThowBadArrayIndex in a COMPOUND_EXPR as no longer needed.
	(java_check_reference): Annotate COND_EXPR with __builtin_expect
	to indicate that calling _Jv_ThrowNullPointerException is unlikely.
	(build_java_arrayaccess): Construct an unlikely COND_EXPR instead
	of a TRUTH_ANDIF_EXPR in a COMPOUND_EXPR.  Only generate array
	index MULT_EXPR when size_exp is not unity.
	(build_array_length_annotation): When optimizing, generate a write
	to the allocated array's length field to expose constant lengths
	to GCC's optimizers.
	(build_newarray): Call new build_array_length_annotation.
	(build_anewarray): Likewise.

	(expand_java_multianewarray): Fix whitespace.
	(expand_java_return): Likewise.
	(expand_invoke): Likewise.
	(load_type_state): Likewise.
