[Mesa-dev] [PATCH] i965: Compile with -msse3

[Matt Turner]

All CPUs that can be paired with a GPU supported by i965_dri.so supports
SSE3. This allows us to ensure that some vectorized version of the tiled
memcpy path is enabled on 32-bit systems.

This also ensures that __builtin_ia32_clflush is always usable.
