This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
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.

Eliminate boilerplate of having each test manually assign to `mydir` by calling
`compute_mydir` in lldbtest.py.

Skip on linux+arm for now until I can try to repo the setup of the
lldb-arm-ubuntu bot. The name of the binary in argv[0] was not
able to be retrieved here; if the compiler's codegen had it stored
in a caller saved register, because it's not needed at this point,
it may not be retreivable.
When looking for a variable location in a DWARF location list,
we search the list of ranges to find one that includes the pc.
With a function mid-stack, the "pc" is the return pc instead of
the call instruction, and in optimized code this can be another
function or a different basic block (with different variable
locations). Back up the "pc" value mid-stack to find the correct
location list entry.
