compiler, rtl: some rtti related changes:
  - write pint instead of 32 bit for record field offset (compiler uses aintsize = pint in TRecordDef), use PtrInt in RTL for record reading
  - add tkRecord to TTypeData (field and type names are taken from Delphi help)
  - add tkProcedure as alias to tkProcVar
