radeonsi: Use unique names for referring to texture sampling intrinsics.

Append the overloaded vector type used for passing in the addressing
parameters.

Without this, LLVM uses the same function signature for all those types,
which cannot work.

Fixes problems e.g. with FlightGear and Red Eclipse.
