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
