glsl: lower double optional passes (v2)

These lowering passes are optional for the backend to request, currently
the TGSI softpipe backend most likely the r600g backend would want to use
these passes as is. They aim to hit the gallium opcodes from the standard
rounding/truncation functions.

v2: also lower floor in mod_to_floor
