Teaches `llvm-dwarfdump` the `--tag=<tag>` option, which allows
for filtering of DIEs by their `DW_TAG_` values in a manner similar
to the current `--name=<pattern>` option.

`--tag=<tag>` can be composed with `--name=<pattern>`, allowing
uses like discovering every subprogram DIE that contains the
pattern `Vector`:

  llvm-dwarfdump --tag subprogram --name Vector --regex some-binary
