a9a2d3d98d New frsqrte implementation; verified accurate.
This is similar to the old implementation, but it uses smaller tables, and
handles more edge cases correctly.  (hwtest coming soon.)

567724b2f8 Jit: get rid of incorrect implementations of fres and frsqrte.
The existing implementations produce answers which aren't consistent with
the hardware, and games care about correct floating point math.

These can be reimplemented at some point in the future, if someone cares
enough, but the general case is probably too much code to inline.

(I'm leaving the ARM implementations in place by request, even though they
suffer the same issues.)

2f8a147eda Interpreter: make fres match hardware.
New table-based implementation written based on actual hardware behavior.

ad4ad7c1ed Use accurate frsqrte in Interpreter.
The implementation of frsqrte exposed by this change isn't completely
correct; that will be fixed in a later commit.

452cdefaa3 Use std::make_unique where it makes sense to

8014795d56 DVD emulation: make seek timing more accurate.
Based on real measurements of a Gamecube disk on a Wii.  (If anyone else
is interested in running more tests, I can upload my code; it's a mess at
the moment.)

This isn't a complete model, but it's a step in the right direction:
in Metroid Prime, the loading times are sane, and I think I managed to do it
without breaking anything.

e659f5ac58 JitBackpatch: fix NOP padding
The new NOP emitter breaks when called with a negative count. As it
turns out, it did happen when deoptimizing 8 bit MOVs because they are
only 4 bytes long and need no BSWAP.

94497961ac Removes unused argument in Helper_UpdateCR1.
Interpreter::Helper_UpdateCR1 doesn't use the argument passed to UpdateCR1. It pulls its value from the FPSCR register.
Also there was a Interpreter::Helper_UpdateCR1(float) in addition to Helper_UpdateCR1(double) that hasn't ever existed. Remove the function
declaration.

c29961cc90 Fix missing instructions in ARM JIT Tables.
The ARM insturction tables were missing addcox, addeox, and subfcox.
Implements support for addcox and addeox to the ArmJit, required little work since they are basically the same as addcx and addex.
