306809f292 [Reproducers] Capture return values of functions returning by ptr/ref
For some reason I had convinced myself that functions returning by
pointer or reference do not require recording their result. However,
after further considering I don't see how that could work, at least not
with the current implementation. Interestingly enough, the reproducer
instrumentation already (mostly) accounts for this, though the
lldb-instr tool did not.

This patch adds the missing macros and updates the lldb-instr tool.

8c436ce3a1 [Reproducers] Add more logging to reproducer instrumentation
Debugging issues with instrumentation capture and replay can be
particularly tricky, especially because part of the process takes places
even before the debugger is initialized. This patch adds more logging
capabilities to these classes, hidden behind a macro define.

76016ba1ca Fix some warnings introduced in r353324 (ReproducerInstrumentation patch)
GetIndexForObjectImpl generated a bunch of "conversion casts away
constness warnings". Change the function to use "const void *" (and
static_cast, while I'm at it), to avoid this.

Driver.cpp: unused variable "replay" (this was actually caused by a
subsequent partial revert of this patch). I just finish the revert by
removing the variable completely.

58947cf854 [Reproducers] SBReproducer framework: Capture & Replay
This is part two of the reproducer instrumentation framework. It
contains the code to capture and replay function calls. The main user of
this framework will be the SB API layer.
