[Mesa-dev] [PATCH 4/5] ra: Don't use regs as the ralloc context.

[Matt Turner]

The i965 backends pass something out of 'screen', which is allocated
per-process, making using this as a ralloc context not thread-safe.

All callers ra_alloc_interference_graph() already ralloc_free() its
return value.
