i915g: Implement writemask fixup
The fixup code emulates non-BGRA render targets by adding an
extra instruction at the end of fragment shaders to swizzle the
output. To do this, we also swizzle the blend function. However
an oversight until now was that the writemask wasn't getting
swizzled. This patch fixes that which fixes a bunch of piglit
tests.
