cffa848b99 Merge pull request #390 from magumagu/fp-reciprocal

d0ed3b8192 Jit: Use infinity and NaN from numeric_limits. 
MSVC's implementation of INFINITY is unusable.

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.)

d08abfc14e JIT: JitBaseBlockCache::InvalidateICache no longer memsets iCache memory to INVALID_BYTE. 
This is redundant, since we reset the valid_block bits any way.
However, this was a source of a significant performance issues in some games.
In particular, Metal Gear Solid: Twin Snakes.

de1e2127dc JIT: JitBaseBlockCache::valid_block is now std::vector<bool> 
This was previously a std::bitset, which resulted in generation of suboptimal code by VS2013 compiler.

2f8a147eda Interpreter: make fres match hardware.

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.

cdec575bef Fixes games that use the MMU to page in code(Rogue Leader). 
The issue was that on memory exception we wouldn't call in to PPCAnalyst and our code_block would retain the previous blocks information.
This would cause us to compile the previous blocks instructions in prior to the exception exit.

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.

727ef4a625 JIT: unify JitAsm for JIT64 and JIT64IL. 
Having a bunch of nearly identical code sitting around isn't a good idea,
so fix that. JITIL had a couple of extra entry points into the JIT main
loop, so adjust the code appropriately.

Also fixes Issue 7186.

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.

f254fdfd96 drop Host_GetKeyState 
This function isn't used any more and it shouldn't be used at all as it generates a sync request to the x11 server. So it has to wait for a complete round trip time.
