Summary	05914: SH-2: watchpoints prevent SH-2 DRC code cache flush
Description	When watchpoints are set, and the SH-2 CPU reaches a page that was executed previously but was modified later, the old content is still executed.
Steps To Reproduce	mame seabass -debug bp 6010000 wpset 0x600ffc0 [run] when breakpoint is hit first, step a few times, and note that R0 and R3 are altered. [run] when breakpoint is hit second, step a few times, and see that R0 and R3 are altered, instead of R7, R5, and R6.
Additional Information	seabass is just an example driver that shows the issue, nothing to do with the bug itself. continuing execution eventually results in stack overflow when it hits a block of CC bytes.
