Sped up the Dolphin debugger in JIT mode by splitting a block only while stepping or when it contains a breakpoint. The block is invalidated when a breakpoint is set or cleared.

Fixed a bug in the JitCache where the JIT icache was not being invalidated when a block containing the instruction was destroyed.
