Pull in r215352 from upstream llvm trunk (by Tim Northover):
AArch64: add support for dynamic-loader relocations
LLD needs them, and it's good to be able to print them properly when
our object dumpers encounter them.
Patch by Daniel Stewart.
This is needed for supporting the upgrade to a newer LLDB snapshot.
Introduced here: http://svnweb.freebsd.org/changeset/base/275152
