Unnormalized integer formats now all use the same path

Integer formats are: UInt32/Int32/UInt16/Int16/UInt8/Int8
The 32 bit formats required using the floating point path for precision,
while the 16 bit and 8 bit formats were going through the short integer
path. Since all formats need to be treated as Int within a 32 bit Float
in the end, this cl unifies all integer formats under the same path.

Related dEQP tests are: functional.texture.format.sized.2d.*
