[nem-en] Please, describe variables...

[vc]

Hi,

Please, describe following variables:
      Typer_checked_macro = null;
      Typer_unchecked_macro = null;
      Typer_yield_macro = null;
      Typer_BetterTypeCache.Clear ();
      StaticTyVarId = 0;
      Typer_DT_Id = 0;
      TyVar_Id = 0;
      TyVar_reuse_queue = null;
      Util_Id = 0;
      AttributeMacroExpansion_global_nr = 0;
      Macros_in_pattern = false;
      Message_error_cnt = 0;
      Message_warning_cnt = 0;
      Message_emitted_hints.Clear ();

In VS Integration we not reset NamespaseTree (we only remove TypeBuilders
from it) and method KillStatics() reset Util_Id. It cause bad match in cases
like:
tc.Equals (InternalType.Object_tc)

I try splitting it method to too. But I not fully understand what do each
variable.
