Small correction to IVB-GPU article

I just updated my article on Ivy Bridge to reflect some corrections I received regarding the GPU.

Specifically:

1. The L1 texture cache is 24KB, not 16KB.
2. The L3 cache and URB share a 512KB data array. Half is tagged for the L3 cache, the other half is explicitly accessed and used for the URB and OpenCL shared memory.

The latter point in particular is helpful to understanding how the memory hierarchy is constructed.
