mesa/get: Make GetFloat/GetDouble of TYPE_INT_N not normalize things.
GetFloat of integer valued things is supposed to perform a simple
int -> float conversion. INT_TO_FLOAT is not that. Instead, it
converts [-2147483648, 2147483647] to a normalized [-1.0, 1.0] float.
This is only used for COMPRESSED_TEXTURE_FORMATS, which nobody in
their right mind would try and access via glGetFloat(), but we may
as well fix it.
Found by inspection.
v2: Gotta catch 'em all (fix another case of this caught by Ilia)
