x64FPURoundMode: use fesetround() instead of asm
x64FPURoundMode: always set x87 precision

Set the x87 precision, even on x64. Since we are using x87 instructions
in the JIT now, we can't guarantee that x87 precision will never
influence Dolphin on x64.

Gameini updates.
VideoCommon: fix indirect texture coordinate computation in TEV.

Even if an indirect texture stage doesn't actually sample a texture, we
still need to emit the relevant math.

Fixes Issue 7092.
VideoCommon: correctly compute whether an indirect texture stage is active.

This is consistent with the implementation in PixelShaderGen.
Enables usage of GLSL textureSize on Qualcomm v66.

Qualcomm's v66 drivers have a working textureSize() function now.
Enable usage of it.
Merge pull request #344 from magumagu/tev-indirect

VideoCommon: fix indirect texture coordinate computation in TEV.
Merge pull request #345 from Sonicadvance1/Qualcomm-textureSize

Enables usage of GLSL textureSize on Qualcomm v66.
VideoInterface: accurate XFB width and height.

What we call "fbWidth" here is really the stride, but I'll fix that in a
followup.
VideoCommon: recreate XFB texture when the XFB size changes.

We need to do this to correctly deal with games which dynamically change the
XFB width and height.
VideoInterface: clean up naming and bitfields.

Matching the hardware more closely will hopefully make this code easier to
read.
