[PATCH, ARM] fix native build warnings on ARM

[Richard Earnshaw]

Clearly nobody has done a native build of the ARM compiler for a while
(ie since March :-).

This patch fixes the warnings that have been introduced since then.

2008-12-19  Richard Earnshaw  <rearnsha@arm.com>

	PR bootstrap/38578
	* arm.c (load_multiple_sequence): Initialize ORDER array.
	(store_multiple_sequence): Likewise.
	(output_move_double): Make reg0 unsigned.
	(arm_output_epilogue): Make amount unsigned.
	(arm_expand_prologue): Move declaration of dwarf before block
	statements.
