[arm] Remove obsolete FPA support (6/n): fix warnings

[Richard Earnshaw <rearnsha at arm dot com>]

[I composed this message on Friday, before I left for the weekend, but
somehow forgot to press send.  The good news is that as a result I can
now confirm that this has fixed the outstanding bootstrap issue.]

This patch cleans up some build warnings that break native bootstrap.
One of the warnings wasn't related to my changes (the iwmmxt one), but
the rest are mine.  Mea culpa!

	* arm.c (note_invalid_constants): Don't return a result.
	(arm_memory_load_p): Delete function.
	(arm_const_double_rtx): Delete iterator variable i;
	(fp_immediate_constant): Likewise.
	(fp_const_from_val): Likewise.

	* arm.c (arm_init_iwmmxt_builtins): Delete void_ftype_void.

R.
