Zachary Turner c432c8f856 Move lldb/test to lldb/packages/Python/lldbsuite/test.
This is the conclusion of an effort to get LLDB's Python code
structured into a bona-fide Python package.  This has a number
of benefits, but most notably the ability to more easily share
Python code between different but related pieces of LLDB's Python
infrastructure (for example, `scripts` can now share code with
`test`).

Test calling user defined functions using expression evaluation.

LLDBs current first choice of evaluating functions is using the IR interpreter,
which is only supported on Hexagon. Otherwise JIT is used for the evaluation.
