Renames TableManager's appendEntry method to registerPreExistingEntry and adds
a comment to explain its purpose. (TableManager subclasses are required to
implement a createEntry method which also appends entries to the map: this
rename aims to avoid any confusion between these methods)
D149522 introduced target features to LinkGraph. However, to avoid a
public dependency on MC, the features were stored in a std::vector
instead of using SubtargetFeatures directly.
Since SubtargetFeatures was moved from MC to TargetParser (D150549), we
can now use it directly to store the features. This patch implements
that and removes the (private) dependency on MC.

This patch introduces a skeleton JITLink ppc64 support header and ELF/ppc64
backend. No relocations are supported in this initial version, but given a
program requiring no relocations (e.g. one that just returns a constant value
from main) the new backend is able to construct a LinkGraph from a ppc64 ELF
relocatable object, and the llvm-jitlink tool is able to execute it.
This commit should also serve as a good example of how to introduce a JITLink
backend for a new architecture.
