Add TestTargetAPI.py:
// When stopped on breakppint 1, and then 2, we can get the line entries using
// SBFrame API SBFrame.GetLineEntry(). We'll get the start addresses for the
// two line entries; with the start address (of SBAddress type), we can then
// resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress().
//
// The two symbol context should point to the same symbol, i.e., 'a' function.
Add two utility functions to lldbutil.py:
o get_stopped_threads(process, reason):
return the list of threads with the specified stop reason or an empty list if not found
o get_stopped_thread(process, reason):
return the first thread with the given stop reason or None if not found
