represent pointers and arrays by adding an extra parameter to the
SBValue
SBValue::GetChildAtIndex (uint32_t idx,
DynamicValueType use_dynamic,
bool can_create_synthetic);
The new "can_create_synthetic" will allow you to create child values that
aren't actually a part of the original type. So if you code like:
int *foo_ptr = ...
And you have a SBValue that contains the value for "foo_ptr":
SBValue foo_value = ...
You can now get the "foo_ptr[12]" item by doing this:
v = foo_value.GetChiltAtIndex (12, lldb.eNoDynamicValues, True);
Normall the "foo_value" would only have one child value (an integer), but
we can create "synthetic" child values by treating the pointer as an array.
Likewise if you have code like:
int array[2];
array_value = ....
v = array_value.GetChiltAtIndex (0); // Success, v will be valid
v = array_value.GetChiltAtIndex (1); // Success, v will be valid
v = array_value.GetChiltAtIndex (2); // Fail, v won't be valid, "2" is not a valid zero based index in "array"
But if you use the ability to create synthetic children:
v = array_value.GetChiltAtIndex (0, lldb.eNoDynamicValues, True); // Success, v will be valid
v = array_value.GetChiltAtIndex (1, lldb.eNoDynamicValues, True); // Success, v will be valid
v = array_value.GetChiltAtIndex (2, lldb.eNoDynamicValues, True); // Success, v will be valid

clang/gcc/llvm-gcc. If the first breakpoint is due to stop at an inlined
frame, test that the call site corresponds to where it should be. Also add
an expecr for a second break stop, if the first break stop corresponds to an
inlined call frame #0.

is just wrong and resulted in the inferior's output getting mixed into the GDB remote communication's
log file. Change all test cases to not pass os.ctermid() and either use SBTarget.LaunchSimple() or
SBTarget.Launch() and pass None as stdin_path/stdout_path/srderr_path to use a pseudo terminal.

before issuing API calls to find the global variable and to get its value.
rdar://problem/9700873 has been updated to reflect the latest status. The dwarf case
now does not seg fault if the inferior is not started; instead, for dwarf case, the
value retrieved from the global variable is None.

Add a usage example of SBEvent APIs.
o SBEvent.h and SBListener.h:
Add method docstrings for SBEvent.h and SBListener.h, and example usage of SBEvent into
the class docstring of SBEvent.
o lldb.swig:
Add typemap for SBEvent::SBEvent (uint32_t event, const char *cstr, uint32_t cstr_len)
so that we can use, in Python, obj2 = lldb.SBEvent(0, "abc") to create an SBEvent.

Fixed crashes for SBValue fuzz calls.
And change 'bool SBType::IsPointerType(void)' to
'bool SBType::IsAPointerType(void)' to avoid name collision with the static 'bool SBType::IsPointerType(void *)'
function, which SWIG cannot handle.

Assign the test method name to self.testMethodName. This can be useful for the
test directory (see test/types for a good example) which houses a bunch of executables
compiled from different source files. The default build action is to create a.out as
the binary executable, which can confuse the module cacheing mechanism and result in
the debugger getting a stale image as the target to be debugged, and chaos ensues.
o AbstractBase.py, TestThreadAPI.py:
Use self.testMethodName to our advantage.
o TestLoadUnload.py:
Add expected failure marker to test case test_modules_search_paths().

after initial construction.
There are two exceptions to the above general rules, though; the API objects are
SBCommadnReturnObject and SBStream.

For the print_stacktrace(thread, string_buffer = False) function, if we have debug info
for a frame function, let's also emit the args for the current function.
o TestFrameUtils.py:
Add stronger assertTrue for frame0's args.
o TestPrintStackTraces.py:
Launch the inferior with ["abc", "xyz"] and expect '(int)argc=3' in the stack traces, since
by design the inferior is built with debug info.
