[patch] dwarf2out.c: VECify used_rtx_varray.

[Kazu Hirata]

Hi,

Attached is a patch to VECify used_rtx_varray.

Since used_rtx_varray won't be a VARRAY after the conversion, I
changed the name to used_rtx_array.

Tested on i686-pc-linux-gnu.  I'll wait for 24 hours just in case
before I'll check in this patch.

	* dwarf2out.c (used_rtx_varray): Rename to used_rtx_array.
	Change the type to VEC(rtx,gc)*.
	(mem_loc_descriptor, add_const_value_attributes,
	dwarf2out_init): Adjust uses of used_rtx_varray.
