This allows for the translation of partial stack traces that do not
include the instructions header line.

Now when -v/--verbose is used, we will also print call information
when those calls appear in stubs that do not correspond to Dart code.
The returned information contains the name of the stub (the name of
the static symbol in the ELF file generated for the stub) as well as
the offset of the frame PC within the stub payload.
This change also adds a flag --dump-debug-file-contents that
outputs the parsed information from the file passed via -d/--debug.

The Dart VM uses two dynamic symbols, _kDartVmSnapshotInstructions and
_kDartIsolateSnapshotInstructions, to store the virtual addresses of the
start of these sections. By using these symbols to find the sections,
we don't bake in the assumption that the two sections appear as distinct
.text segments or an assumption about the order in which they appear.
