v2: use uint64_t for the total_size variable, per Jose.
Also add two earlier checks for exceeding the max texture size.
For example a 1K^3 RGBA volume would overflow the lpr->image_stride
variable.
Use simple algebra to avoid overflow in intermediate values.
So instead of "x * y > z" use "x > z / y".
This should work if we happen to be on a platform that doesn't have
64-bit types.

This was already (correctly) supported for glGetSamplerParameter paths.
NOTE: This is a candidate for stable branches.

Initializing the regalloc state is expensive, and since it is always
the same for every compile we only need to initialize it once per
context. This should help improve shader compile times for the driver.
Compute shaders fetch data from vertex buffers via the texture cache, so
we need to make sure the texture cache is flushed.

- Fix rebase mistake
- Fix spelling in comment

LOOP_START_DX10 ignores the LOOP_CONFIG* registers, so it is not limited
to 4096 iterations like the other LOOP_* instructions. Compute shaders
need to use this instruction, and since we aren't optimizing loops with
the LOOP_CONFIG* registers for pixel and vertex shaders, it seems like
we should just use it for everything.

For buffers (which is what is being used for RATs), the
COLOR*_DIM.WIDTH_MASK field needs to be set to the low 16-bits of the
buffer size, and the COLOR*_DIM.HEIEGHT_MAX needs to be set to the
high bits.

Don't cache pointers to elements of reallocatable array.
In some circumstances it caused false cache hits resulting in incorrect
command stream and gpu lockup.
