Swift types have mangled names, so there should be a way to read those from the
compiler type.
This patch upstreams these two changes from swiftlang/llvm-project (which were
added there since at least 2016).

Subject: [PATCH] [lldb] Add GetMangledTypeName to TypeSystem/CompilerType
Swift types have mangled names, so there should be a way to read those
from the compiler type.
This patch upstreams these two changes from swiftlang/llvm-project
(which were added there since at least 2016).
