  Log Message:
  -----------
  [llvm-dwarfdump][Statistics] Count more than one conrete out-of-line instances of a function

Here may be more than one out-of-line instance of the same function
among different CUs. All of them should be accounted for to get an accurate
total number of variables/parameters.

  Log Message:
  -----------
  [llvm-dwarfdump][Statistics] Distinguish parameters with same name or w/o a name

A few DW_TAG_formal_parameter's of the same function may have the same
name (e.g. variadic (template) functions) or don't have a name at all
(if the parameter isn't used inside the function body), but we still
need to be able to distinguish between them to get correct number of 'total vars'
and 'availability' metric.

  -----------
  [llvm-dwarfdump][Statistics] Make calculations of vars in global scope more accurate

It isn't known how many times we've seen the same variable or member in
the global scope (unlike in functions), but there still can be some duplicates
among different CUs.
So, this patch proposes to count variables in the global scope just as a sum of
the number of vars, constant members and artificial entities.
