python3Packages.mypy: compile with mypyc

Browse source 
Mypy includes mypyc, a compiler that translates annotated Python to C,
which can be compiled into a Python module. When mypy is compiled with
mypyc, it is about 4 times faster than the interpreted mypy, so using
the compiled version is especially useful on large codebases where
typechecking may take a long time.

The wheels distributed on Pypi have included a mypyc-compiled mypy by
default since version 0.700 [1].
