[Mesa-dev] [PATCH 2/2] i965: Bump the initial program cache size from 4kB to 16kB.

[Kenneth Graunke]

Our initial size of 4kB is way too small to do anything useful, so we
end up growing it at least a few times.  We may as well start it larger.

Some data points:

- Dinoshade (from Mesa Demos): hit 8kB.
- Chromium 60: hit 16kB after browsing a few things in Google Docs.
- GFXBench4 TRex/Manhattan 3.1: hit 128kB
- Unigine Valley 1.0: hit 512kB

It might make sense to start it even larger.
