last change Replace fpscr_mask/fpscr flags in xlat_cache_block with a single xlat_sh4_mode,
which tracks the field of the same name in sh4r - actually a little faster this way.
Now depends on SR.MD, FPSCR.PR and FPSCR.SZ (although it doesn't benefit from the SR
flag yet).

Also fixed the failure to check the flags in the common case (code address returned
by previous block) which took away the performance benefits, but oh well.
