Andres Freund 6c57f2ed16 jit: Add support for LLVM 12. 
LLVM 12, to be released in a few months, made some breaking changes to
the Orc JIT interface. OrcV2 eventually will make it easier to support
features like concurrent JIT compilation, but this commit only allows
to compile against LLVM 12.

This commit is a bit bigger than desirable. That partially is because
the V2 interface is more granular than V1 interface, but also because
I chose to make some minor changes to < LLVM 12 code to keep the code
somewhat readable.

The LLVM 12 support will need to be backpatched. I plan to do so after
the patch stewed on the buildfarm for a few days.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	https://www.postgresql.org/download/

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
