[Mesa-dev] [PATCH 06/40] glsl: add helper to convert pointers to uint64_t

[Timothy Arceri]

From: Timothy Arceri <timothy.arceri at collabora.com>

This will be used to store all pointers in the cache as 64bit ints
allowing us to avoid issues when a 32bit program reads a cached
shader that was created by a 64bit application.
