[Mesa-dev] [PATCH 6/9] i965/fs: Don't CSE render target messages with different target index.

[Francisco Jerez]

We weren't checking the fs_inst::target field when comparing whether
two instructions are equal.  For FB writes it doesn't matter because
they aren't CSE-able anyway, but this would have become a problem with
FB reads which are expression-like instructions.
