Numba

---------------------

This release predominantly upgrades to LLVM 14 and Python 3.11.
Bindings to a large number of passes are added.
The minimum supported Python version is now Python 3.8.

Note: A bug was discovered in LLVM's RuntimeDyldELF on the Aarch64 platform that
can cause segfaults when cross module symbols are linked. It is necessary
for JIT users to build LLVM with the patch added in
`PR926 <https://github.com/numba/llvmlite/pull/926>`_.

-----------------------

This release predominantly adds new features and improves functionality.

* It's now possible to directly set LLVM ``metadata`` on global variables.
* Functions and global variables now support the specification of a ``section``
in which they should be placed.
* The attribute ``source_file`` had been added to the ``ModuleRef`` class, it
returns the module's original file name.
* The FFI library binding to LLVM is now loaded with ``importlib`` to increase
compatibility with other projects and improve start-up times.
* Linux builds now use the parallel option to ``make`` to speed up building the
FFI library.
* Preliminary work to expose LLVM's optimization-remarks interface has been
undertaken. The bindings are exposed and tested, but not yet documented for
general use (additional work is needed).

Deprecations:

* The ``llvmlite.llvmpy`` module has been deprecated as the functionality it
provides is available through the ``llvmlite.ir`` module. See the deprecation
guide in the user documentation for details and recommendations regarding
replacement.

This release makes llvmlite compatible with Python 3.10. It also adds an
``abiname`` option to the target machine creation interface that mimics the same
in LLVM. Further, a large number of functions are added to the IR API to support
common uses of constant expressions. Finally, a number of bugs were fixed!

-------------------------

The biggest new feature in this release is LLVM 11 support for all platforms!
This is important, because the ``aarch64`` platform had been 'stuck' on LLVM 9
for several releases. A special thanks to David Spickett from Linaro for
supplying the relevant patch.
