Add IR support, ELF section and user documentation for partitioning feature.
The partitioning feature was proposed here: http://lists.llvm.org/pipermail/llvm-dev/2019-February/130583.html This is mostly just documentation. The feature itself will be contributed in subsequent patches. Differential Revision: https://reviews.llvm.org/D60242 llvm-svn: 361923

+``SHT_LLVM_SYMPART`` Section (symbol partition specification)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This section is used to mark symbols with the `partition`_ that they
+belong to. An ``.llvm_sympart`` section consists of a null-terminated string
+specifying the name of the partition followed by a relocation referring to
+the symbol that belongs to the partition. It may be constructed as follows:
+
+.. code-block:: gas
+
+ .section ".llvm_sympart","",@llvm_sympart
+ .asciz "libpartition.so"
+ .word symbol_in_partition
