i965: Use float calculations when double is unnecessary.
Literals without an f/F suffix are of type double, and implicit
conversion rules specify that the float in (float op double) be
converted to a double before the operation is performed. I believe float
execution was intended (in nearly all cases) or is sufficient (in the
case of gen7_urb.c).
Removes a lot of float <-> double conversion instructions and replaces
many double instructions with float instructions which are cheaper.
