i965/fs: Lower integer multiplication after optimizations.
32-bit x 32-bit integer multiplication requires multiple instructions
until Broadwell. This patch just lets us treat the MUL instruction in
the FS backend like it operates on Broadwell, and after optimizations
we lower it into a sequence of instructions on older platforms.
Doing this will allow us to some extra optimization on integer
multiplies.
