i965/fs: Fix conversions float->bool, int->bool
Fixes gles2conform GL.equal.equal_bvec2_frag.
This fixes brw_fs_visitor's translation of ir_unop_f2b. It used CMP to
convert the float to one of 0 or ~0. However, the convention in the
compiler is that true is represented by 1, not ~0. This patch adds an AND
to convert ~0 to 1.
By inspection, a similar problem existed with ir_unop_i2b, with a similar
fix.
[v2 kayden]: eliminate extra temporary register.
