Handle branch delay-slot instruction that falls on the next page correctly.
- Generate the right end PC in the first place (sh4trans.c)
- Allow blocks to be marked as both entry point + continuation, and
specifically handle invalidation when first entry of a page is a continuation ==
flush previous page as well.

SH4 shadow-mode tweaks
- Fix exceptions generated by the translator to account for the excepting
instruction(s) in the cycle counts.
- Compare floating point regs bitwise rather than with FP comparisons
(otherwise can fail due to nan != nan)
- Dump the translated block when we abort with an inconsistency
