i965/vs: Add support for textureGather(.., comp)

- For HSW: Select the channel based on the component selected (swizzle
  is done in HW)
- For IVB: Select the channel based on the swizzle state for the
  component selected. Only apply the RG32F w/a if we actually want
  green -- we're about to flag it regardless of swizzle state.
