Subject: Define AT as UChar in VEX/priv/guest_ppc_toIR.c (dis_vsx_accumulator_prefix)

Define AT as UChar in VEX/priv/guest_ppc_toIR.c (dis_vsx_accumulator_prefix)

GCC notices that AT is passed around as char, specifically as %u argument
to DIP. But ifieldAT returns an UChar and vsx_matrix_ger takes AT as UChar.
This causes lots of format string warnings when building with GCC11.

Simply declare AT as UChar instead of char.
