Move the iteration protocol of lldb objects to the auto-generated lldb Python module.
...
This is so that the objects which support the iteration protocol are immediately obvious
from looking at the lldb.py file.
SBTarget supports two types of iterations: module and breakpoint. For an SBTarget instance,
you will need to issue either:
for m in target.module_iter()
or
for b in target.breakpoint_iter()
For other single iteration protocol objects, just use, for example:
for thread in process:
ID = thread.GetThreadID()
for frame in thread:
frame.Disassemble()

libstdc++ 4.4 uses __is_signed as an identifier, while Clang treats it
...
as a keyword for the __is_signed type trait. Cope with this conflict
via some hackish recovery: if we see a declaration of the form
static const bool __is_signed
then we stop treating __is_signed as a keyword and instead treat it as
an identifier. It's ugly, but it's better than making the __is_signed
type trait conditional on some language flag. Fixes PR9804.

Fix the last -Wnon-pod-memset I'm seeing. This is benign, but appears

a bit more sinister as the memset doesn't do what the constructor does.
There seems to be a cleaner solution than a cast here though, instead we
can point the memset destination into the union its actually trying to
clear.
An alternative is to point to the Untyped member of this union. Review
appreciated, and if that is cleaner I'm happy to switch. All of these
should be functionally equivalent to the original code.
