last change	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
