After D154102 multi-line labels would get split incorrectly.
When CFG is generated for a function with basic block name longer
than 80 lines, then the header separator will be placed after the
line break for the label name instead of after the whole label name.
The fix is simple by just moving the insert of | character before the
line splitting happens.

This change adds separators for basic block names, which makes it
easier to find a basic block based on its name and separates it
from the code.
Currently there is also a chance that the basic block label will
be present twice, that is in case the basic block has explicit
numbering, this change fixes this bug.

This is a follow-up to b71edfaa4ec3c998aadb35255ce2f60bba2940b0
since I forgot the lit.local.cfg files in that one.
Reformatting is done with `black`.
If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours <yourfile> and then reformat it
with black.
If you run into any problems, post to discourse about it and
we will try to help.

This pass allows a user to dump a MIR function to a dot file
and view it as a graph. It is targeted to provide a similar
functionality as -dot-cfg pass on LLVM-IR. As of now the pass
also support below flags:
-dot-mcfg-only [optional][won't print instructions in the
graph just block name]
-mcfg-dot-filename-prefix [optional][prefix to add to output dot file]
-mcfg-func-name [optional] [specify function name or it's
substring, handy if mir file contains multiple functions and
you need to see graph of just one]
More flags and details can be introduced as per the requirements
in future. This pass is inspired from -dot-cfg IR pass and APIs
are written in almost identical format.
