Factor out some common logic used to find the runtime library in a list
of modules.

Adapters for instrumentation runtimes have to do two basic things:
1) Load a runtime library.
2) Install breakpoints in that library.
This logic is duplicated in the adapters for asan and tsan. Factor it
out and document bits of it to make it easier to add new adapters.
I tested this with check-lldb, and double-checked
testcases/functionalities/{a,t}san.

For Thread Sanitizer reports, LLDB tries to find a global variable declaration
corresponding to the racy address in order to provide a filename and line
number. This commit changes the lookup of the variable to use the mangled
name for lookup and fall back to the demangled version if unavailable. This
is needed to report locations of races on Swift global variables.
I've also added a test to make sure we look up C++ globals correctly.

This patch adds ThreadSanitizer support into LLDB:
- Adding a new InstrumentationRuntime plugin, ThreadSanitizerRuntime, in the same way ASan is implemented.
- A breakpoint stops in `__tsan_on_report`, then we extract all sorts of information by evaluating an expression. We then populate this into StopReasonExtendedInfo.
- SBThread gets a new API, SBThread::GetStopReasonExtendedBacktraces(), which returns TSan’s backtraces in the form of regular SBThreads. Non-TSan stop reasons return an empty collection.
- Added some test cases.
