i965/fs: add support for shader float control to remove_extra_rounding_modes()
The remove_extra_rounding_modes() optimization will remove duplicated
rounding mode changes.
v2:
- Fix bug in the rounding mode change (Alejandro).
v3:
- Fix rounding modes.
v4:
- Updated to renamed shader info member and enum values (Andres).
v5:
- Simplify flags logic operations (Caio).
