[Mesa-dev] [PATCH 15/24] i965/fs: Set stride = 1 for vector immediate types.

[Matt Turner]

The generator asserts that this is true (and presumably it's useful in
some optimization passes?) and the VF fs_reg constructors did this (by
virtue of the fact that it doesn't override what init() does).

In the next commit, calling this constructor with brw_imm_* will
generate an IMM file register rather than a HW_REG, making this change
necessary to avoid breakage with existing uses of brw_imm_v().
