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).

2d3df5c621 armjit: Handle divide by zero more accurately. 
Turns out, some games may depend on this behavior.

a05ae2a0a6 Correct divide by zero HI/LO values a bit. 
Interpreter is now correct, but it's probably not all that important to
get right in jit.

cdddd4b59c Fix an undefined bit shift. 
Shouldn't have mattered anyway, but maybe this can crash some ARM chip or
something...

05a8e2e35d Some work towards being able to build two JITs together 
This will be useful for testing/debugging, but not there yet.

5a89c17cf0 armjit: Allow R1 in regalloc, use LR as temp. 
LR should be safe, although it may make stack traces not work within jit,
they don't really tend to work anyway.

b53143bb33 Revert "armjit: Skip an AND for rotate shifts." 
This reverts commit ab2dd54ade.

Even though the docs say it's safe but apparently not always.

e783627947 armjit: Use our I2R funcs on reg/reg math too. 
When one is a known immediate.  This should catch more cases, like:

ori v0, $0, 0xFFFF
and v1, v1, v0

8e979da0f9 armjit: Use our I2R arm optimizations. 
Should help cases of ori and andi most, but also addiu.  They will all try
to use an optimized immediate (from another nearby value) if possible.

dffa35ef2f When ins is used with a zero argument, don't OR. 
Seems it's used effectively to mask out bits with rs=zero.  Makes sense...

7e46ee0b0f armjit: Replace MOVI2R with using the regcache. 
So that it can optimize the value with existing imms.

Not actually optimizing yet.
