i965/fs: Add a concept of a width to fs_reg
Every register in i965 assembly implicitly has a concept of a "width".
Usually, this is derived from the execution size of the instruction.
However, when writing a compiler it turns out that it is frequently a
useful to have the width explicitly in the register and derive the
execution size of the instruction from the widths of the registers used in
it.
This commit adds a width field to fs_reg along with an effective_width()
helper function. The effective_width() function tells you how wide the
register effectively is when used in an instruction. For example, uniform
values have width 1 since the data is not actually repeated, but when used
in an instruction they take on the width of the instruction. However, for
some instructions (LOAD_PAYLOAD being the notable exception), the width is
not the same.

Previously, we were generating the fast-clear shader from GLSL. The
problem is that fast clears require that we use a replicated write rather
than a regular write instruction. In order to get this we had a
complicated and somewhat fragile optimization pass that looked for places
where we can use a replicated write and used it. Since replicated writes
have a lot of restrictions, we only ever use them for fast-clear
operations.
This commit replaces the optimization pass with a function that just

the optimization pass, and c) generates a more efficient shader.

vc4: Don't try to do stores to buffers that aren't bound.
The code was kind of mixed up what buffers were getting stored in the case
that a resolve bit was unset (which are set based on the GL state at draw
time) and the buffer wasn't actually bound. In particular, depth-only
rendering would store the color buffer contents, which happen to be
pointing at the depth buffer.
Thanks to clearing out the resolve bits for things we really can't
resolve, now I can drop the safety checks for buffer presence around the
actual stores.
