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

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.
