A regression (?) with --gc:arc and repr

repr doesn't work with a File object on devel

Example

# Compile with nim c --gc:arc file.nim
import os
var a: File
echo repr a

Current Output

/home/dian/stuff/nim-cephei/test.nim(5, 11) Error: ambiguous call; both repr_v2.repr(x: ref T or ptr T) [declared in /home/dian/.nim/lib/system/repr_v2.nim(106, 6)] and repr_v2.repr(x: ptr T) [declared in /home/dian/.nim/lib/system/repr_v2.nim(102, 6)] match for: (File)

Nim compiler hash is fc5dd11

I think narimirans fix is correct, but there is also a sigmatch issue.. I think ptr T shouldn't be ambiguous with ptr T or ref T as ptr T is more specific.

not 100% sure whether it's already covered in https://nim-lang.github.io/Nim/manual.html#overloading-resolution but I disagree, sigmatch is correct in this case and I see no use case for A overloading A or B (it just indicates library error)

From the manual:

Likewise for generic matches the most specialized generic type (that still matches) is preferred
