[PATCH 01/11] Rename "variant" to "ppc_variant"

[Tom Tromey]

I wanted to use the name "variant" to represent a DWARF variant, but
it turned out there was an existing structure of that name.  This
renames the existing variant to "ppc_variant".

	* rs6000-tdep.c (struct ppc_variant): Rename from "variant".
	(variants, find_variant_by_arch, rs6000_gdbarch_init): Update.
