bac36df453 x86jit: Refactor and fix jump in branch delay slot. 
This seems cleaner, instead of the duplication of lines for each branch
type.

db2eddcf27 Debugger: Remove double debug window updates. 
Core_EnableStepping() is already marking the debug windows for update,
there's no need to call SetDebugMode() again.

bc16a55028 jit: Count delay slot cycles separately. 
This makes it easier to count cycles per instruction, instead of ignoring
the delay slot's instruction for cycle count.

1b00da2f3a Common: Sign extend w/func not chained casts. 
Should be clearer to read and easier to get right.

c179cad5c2 jit: Make branch shift more obvious. 
And also not technically undefined behavior.

c5e0b799d9 Remove category from _assert_msg_ functions. We don't filter these by category anyway. 
Fixes the inconsistency where we _assert_ didn't take a category but
_assert_msg_ did.

ae224b3893 jit: Add some basic checks in armjit/arm64jit. 
Just the simple (and unlikely) case so far...

b3bf61dde1 x86jit: Trigger exec exceptions. 
A common case might be, you're hacking something in the game and you broke
the stack, so you `jr ra` into outer space.

8c3552de74 cmake: Detect features at compile time 
Instead of relying on manually passed down flags from CMake,
we now have ppsspp_config.h file to create the platform defines for us.
This improves support for multiplatform builds (such as iOS).

81dec36da8 Use an accessor to read the compilerPC. 
In the IR it will be read from the block.

a897723e6a Separate out jit reading nearby instructions. 
This makes it easier to use an IR for these things, or remove them.

This is a pretty minor optimization, though.

6fae78cd3f x86jit: Fix a bug in branch continuing. 
When we predict it won't take a likely delay slot, we'd lose our register
allocation state.

2f598e8f38 jit: Statically jump for fixed branches. 
This handles both loops (first step is known) and static branches (some
code uses them instead of jumps, and we disassemble that to "b".)

Not likely to be a big improvement, but might help if the branch predictor
was wrong.

This is as opposed to continuing, which would build a larger jit block.

8d0dca71fe jit: Rename the rounding mode funcs to clarify. 
They apply/restore the value, set/clear is confusing.

925557ed47 x86jit: Maintain the rounding mode always. 
This should be less often than doing it per block that uses fpu, unless
the game doesn't use fpu much at all.

dc91dc1ce8 x86jit: Support fpu rounding modes for mul, etc.

1cb7965cb1 Jit feature preparation: Introduce "proxy blocks". 
When these are invalidated, the block they point to gets invalidated too.

Will be useful to implement various types of block merging and function inlining
without affecting correctness of cache clears etc.

Also, with this commit we can now fully inline replaced functions. fabsf() boils
down to 1-2 instructions and the block continues, for example.
