[Mesa-dev] [PATCH 1/4] st_glsl_to_tgsi: bump index back up to 32-bit

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

with some of the fp64 emulation, we are seeing shaders coming in with
> 32K temps, they go out with 40 or so used, but while doing register
renumber we need to store a lot of them.

So bump this fields back up to 32-bit.
