Julian Seward c513ea3cd8 When constructing a signal frame, tell the tool that the registers
that carry the arguments (signo, siginfo, mcontext) for the handler,
have been written.  In particular this makes Memcheck think
(correctly) they are defined and so removes a bunch of false positives
that can happen in the signal handler, should the registers have been
marked undefined before the signal.

The same fix needs to be applied to various other of these
sigframe-*.c files.
