CPU: Add more branch hints to interpreter 
Eliminate more bounds checks. This plus the last change can net up to a
20% performance improvement in some games when using the interpreter
(tested on AMD 7950X3D).

CPU: Use ternary in CPU::WriteRegDelayed() 
Shouldn't make any net difference, a good compiler will turn this into a
cmov anyway.

arbitrary value.

CPU: Clear pending bus error when interpreting block 
It can get set from a failed rec access much earlier.

Also eliminates a redundant store from the main interpreter loop.

CPU: Don't stall until GTE completion on write 
Apparently this is what the real CPU does, and some very optimized
code can run slower if we stall early.

Obviously if you write to a register being read by the command,
things are going to break.

CPU/Interpreter: Address ICache lines in words 
Might help on ARM32, because no unaligned access.

Otherwise, ~23% perf boost in debug builds. But this is pretty
meaningless.

Log: Switch to enum class

horribly slow, and conflict when one is a prefix of another.

CPU: Add SetBreakpointEnabled() 2 years ago

Quality of Life changes to breakpoints (#3297) 
1. Made it so that breakpoints are checked for a match on 28 bits rather than the full 32 bits. It's much simpler to use 12345 rather than 80012345 and risk getting the number of zeros wrong and also handles the mirror code/memory accesses using 00??????, 80?????? & A0??????.
2. Added bp.hit_count update to execution breakpoints.
3. Changed the Hit breakpoint message at the bottom of the debugger screen to include the hit count [see notes later].
4. Added bp.enabled check to the execution breakpoint (it uses it in the r/w breakpoints code already) [see notes later].

Notes:
3. I've added the hit count to the message as it's quicker to spot but it's also a partial workaround as the Hit Count in the Breakpoints tab doesn't seem to get refreshed.
       4. I thought the checkbox in the Breakpoints tab would set the bp.enabled but it seems it has no affect on any type of breakpoint. The only way to stop a breakpoint is to delete it.
