Add support for walrus operator (#935) 
* Parse `:=` properly
* never unwrap parenthesis around `:=`
* When checking for AST-equivalence, use `ast` instead of `typed-ast` when running on python >=3.8
* Assume code that uses `:=` is at least 3.8

9394de150e Fix trailing comma for function with one arg (#880) (#891) 
Modified maybe_remove_trailing_comma to remove trailing commas for
typedarglists (in addition to arglists), and updated line split logic
to ensure that all lines in a function definition that contain only one
arg have a trailing comma.

Move tokenizer config onto grammar, rename flag 
Based on the feedback in
https://github.com/python/black/pull/845#issuecomment-490622711

- Remove TokenizerConfig, and add a field to Grammar instead.
- Pass the Grammar to the tokenizer.
- Rename `ASYNC_IS_RESERVED_KEYWORD` to `ASYNC_KEYWORDS` and
  `ASYNC_IS_VALID_IDENTIFIER` to `ASYNC_IDENTIFIERS`.

Add support for always tokenizing async/await as keywords 
Fixes #593

I looked into this bug with @ambv and @carljm, and we reached the
conclusion was that it's not possible for the tokenizer to determine if
async/await is a keyword inside all possible generators without breaking
the grammar for older versions of Python.

Instead, we introduce a new tokenizer mode for Python 3.7+ that will
cause all async/await instances to get parsed as a reserved keyword,
which should fix async/await inside generators.

Task completion should also remove the task from `pending`.

Only replicates on some platforms. (eg. Can replicate on Python 3.7+, with either Windows or whatever default Linux distro Travis uses.)

Fixes #448.

This diff makes us always write to the cache in normal mode, except
if the file is already in the cache, and it makes us write to the
cache in --check mode if the file is already well formatted.

I also fixed some related docstrings.

WriteBack.NO is now used only in tests.

cc48bc56ca normalize numeric literals (#454) 
Fixes #452

I ended up making a couple of other normalizations to numeric literals
too (lowercase everything, don't allow leading or trailing . in floats,
remove redundant + sign in exponent). I don't care too much about those,
so I'm happy to change the behavior there.

For reference, here is Python's grammar for numeric literals:
