The `Match.operator[]` does the same thing and is
generally recommended (and shorter).
(I want to deprecate `group` and `groups`)
Tested: Refactoring.
CoreLibraryReviewExempt: Calling equivalent function.

Use `hasScheme` in place of comparing against the empty string, and
`isScheme` to compare against all other schemes.
TEST=No behavior changes.

This works on all browsers, in d8, and supports both dartdevk and
dart2js. In the case of dart2js, this also expands minified names and
inlined data.
The result is presented to users as a separate section, so the original
JS stack trace is printed as is, and a second deobfuscated stack trace
is printed afterwards.

This reduce the memory footprint and cost of parsing these extensions. Another
advantage is a reduction on the size of the .map files. On a large customer
app, this was a 11% reduction, and the frames section was about 1Mb (excluding
the extra names and uris added on the existing tables).
The encoding works as follows:
- minified names are written as a list of names and indices, in pairs.
{'n1': 1, 'n2': 2} => 'n1,1,n2,2'
- frames are encoded using a sequence of values with markers for the different
kind of frames. Numbers are encoded using VLQ deltas. We use VLQ because it's
already available to any parser that deals with the mappings).
This change also uses the dart2js_tools parser implementation for all unit tests.

Changes include:
* Added a couple no-such-method decoders.
* Apply deobfuscation rules more than once per line
* Fixed pattern matched for minified names.
* Added support for expanding the call signature from call selectors
* Fix backward search to find the function declaration
* Refactor trace deobfuscation logic:
* add dependency on stack\_trace to parse frames
* add library to expose trace deobfsucation and keep that separate from
printing the results
* Fix off-by-one error when extracting the name of a function whose index is 0.
* Avoid crash if we can't get a function name.

This is an initial implementation of the dart deobfuscator tool.
Let me know your thoughts on the package name. I used to have this named as
`package:deobfuscate`, but it feels like we will want to add more tools that are
not about deobfuscation in the future, so I picked `package:dart2js_tools`
instead. That also gives us the opportunity to move over the dart2js_info code
here too.
