i965/fs: Do CSE on gen7's varying-index pull constant loads.
This is our first CSE on a regs_written() > 1 instruction, so it takes a
bit of extra fixup. Reduces the number of loads on kwin's Lanczos shader
from 12 to 2.
v2: Fix compiler warning (false positive on possibly-uninitialized variable)
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=61554
Reviewed-by: Kenneth Graunke <[email protected]> (v1)
NOTE: This is a candidate for the 9.1 branch.
