lldb/Instrumentation: NFC-ish use GetFrameCodeAddressForSymbolication()

A couple of our Instrumentation runtimes were gathering backtraces,
storing it in a StructuredData array and later creating a HistoryThread
using this data. By deafult HistoryThread will consider the history PCs
as return addresses and thus will substract 1 from them to go to the
call address.

This is usually correct, but it's also wasteful as when we gather the
backtraces ourselves, we have much better information to decide how
to backtrace and symbolicate. This patch uses the new
GetFrameCodeAddressForSymbolication() to gather the PCs that should
be used for symbolication and configures the HistoryThread to just
use those PCs as-is.

(The MTC plugin was actaully applying a -1 itself and then the
HistoryThread would do it again, so this actaully fixes a bug there.)
