gallium: Add TGSI_OPCODE_F2U to gallivm backend.
Note: for the moment TGSI_OPCODE_F2U is implemented using
lp_build_itrunc() (the same function used to implement
TGSI_OPCODE_F2I). In the long run, we should create an
lp_build_utrunc() function to do the proper conversion. But this
should allow us to limp along with mostly correct behaviour for now.
