[Lldb-commits] [PATCH] D67774: [Mangle] Check ExternalASTSource before adding prefix to asm label names

[Vedant Kumar via Phabricator via lldb-commits]

LLDB may synthesize decls using asm labels. These decls cannot have a
mangle different than the one specified in the label name. I.e., the
mangle-suppression prefix should not be added.

Fixes an expression evaluation failure in lldb's TestVirtual.py on iOS.
