[Mesa-dev] [PATCH 20/25] i965/fs: Extend compute_to_mrf() to coalesce VGRFs initialized by multiple single-GRF writes.

This requires using a bitset instead of a boolean flag to keep track of the GRFs we've seen a generating instruction for already. The search loop continues until all instructions initializing the value of the source VGRF have been found, or it is determined that coalescing is not possible. ---
