Revert "Calculate texture clamping X/Y coordinates in parallel."

This reverts commit a38945abe337019886f3b6bdcac4a7e3060870c2.

Reason for revert: Pinpoint says it costs RAM on Mac (?), and doesn't show any visible perf benefit

Original change's description:
> Calculate texture clamping X/Y coordinates in parallel.
> 
> The X and Y values of `clampedCoord`, `extraRepeatCoord`, and `snapped`
> were being calculated and stored separately, even in cases where work
> could easily be done in tandem. Updated the code so that we use .xy when
> it makes sense to do so.
