re PR c/11234 (-pedantic accepts function pointer <-> void*)

	PR c/11234
	* c-typeck.c (build_c_cast): If pedantic, warn for conversions
	between function and object pointers.
	(digest_init): When comparing a pointer to function type to the
	target type, only apply TREE_TYPE once to the pointer to function
	type.
	* except.c (for_each_eh_label_1): Treat data as a pointer to a
	function pointer rather than casting it to a function pointer.
	(for_each_eh_label): Update caller.
	* recog.h (struct insn_data): Use a struct or union for output.
	* genoutput.c (output_insn_data): Update.
	* final.c (get_insn_template): Update.

testsuite:
	* gcc.dg/func-ptr-conv-1.c: New test.
	* gcc.dg/weak/weak-6.c, gcc.dg/weak/weak-7.c: Update.
