  Changed paths:
    M lldb/source/Target/AssertFrameRecognizer.cpp

  Log Message:
  -----------
  The AssertRecognizer used the module from a frames SC without checking it was non-null.

I only have a crash report for this.  I could reproduce it with a slightly older
lldb by running an expression that called pthread_kill, but we started making modules
for our expression JIT code, so that no longer triggers the bug.  I can't think of another
good way to test it but the fix is obvious.
