We were incorrectly computing the buffer offset when using the

start_instance * stride + (instance_num / instance_divisor) *

We were completely ignoring the start instance quite
often producing instances that completely wrong, e.g. if
start instance = 5, instance divisor = 2, then on the first

5 * stride, not (5/2) * stride as we'd have currently, and if

NOTE: This has the side effect of enabling the extension in Gallium
drivers that enable GL_ARB_texture_multisample.

v2 (Ken): Still prevent multisample texture targets in TexParameter for
implementations that don't support multisampling.

In Mesa, this extension is implemented purely in software.  Drivers may
*optionally* provide optimized paths.

NOTE: This has the side effect of enabling the extension in the radeon,
