Peter Maydell c1e0371442 target-arm: ignore ELR_ELx[1] for exception return to 32-bit ARM mode 
The architecture requires that for an exception return to AArch32 the
low bits of ELR_ELx are ignored when the PC is set from them:
 * if returning to Thumb mode, ignore ELR_ELx[0]
 * if returning to ARM mode, ignore ELR_ELx[1:0]

We were only squashing bit 0; also squash bit 1 if the SPSR T bit
indicates this is a return to ARM code.
