The System.Runtime.InteropServices.OutAttribute is a pseudo-custom attribute
and should not be emitted as a normal custom attribute, instead the Out flag of
the parameter should be set.

Reproducible: Always

Steps to Reproduce:
1. vbnc test.vb
2. ildasm test.exe
3. look at foo method
Actual Results:  
method public static void  Foo(int32& i) cil managed
{
  .param [1]
  .custom instance void
[mscorlib]System.Runtime.InteropServices.OutAttribute::.ctor() = ( 01 00 00 00
) 
  // Code size       2 (0x2)
  .maxstack  8
  IL_0000:  nop
  IL_0001:  ret
} // end of method MyMod::Foo



Expected Results:  
method public static void  Foo([out] int32& i) cil managed
{
  // Code size       1 (0x1)
  .maxstack  8
  IL_0000:  ret
} // end of method MyMod::Foo
