  1. [LLVM] Factor disabled Libcalls into the initializer 

    Summary:
These Libcalls represent which functions are available to the backend.
If a runtime call is not available, the target sets the the name to
nullptr. Currently, this logic is spread around the various targets.
This patch pulls all of the locations that disable libcalls into the
intializer. This patch is effectively NFC.

The motivation behind this patch is that currently the LTO handling uses
the list of all runtime calls to determine which functions cannot be
internalized and must be extracted from static libraries. We do not want
this to happen for libcalls that are not emitted by the backend. A
follow-up patch will move out this logic so the LTO pass can know which
rtlib calls are actually used by the backend.
