a4d817dbae Test separately whether g++ and/or gcc support built-in functions for atomic 
memory access. Apparently for some distributions gcc 4.2 has that support but
g++ 4.2 doesn't. This patch has been supplied by Florian Krohm.

aca925fd10 When handling client munmaps and mprotects with r=0 & w=0, actually 
paint the relevant address range as NoAccess rather than ignoring the
event.  This is important for avoiding VTS leaks in libhb_core.
More details in comments in the code.

Also rename the _noaccess_ painters that do nothing to make it clearer
that they do nothing :-)

159af3e3ee NB: this is an temporary fix, until such time as bug 243935 is fully 
resolved.

Add a client request, ANNOTATE_HAPPENS_BEFORE_FORGET_ALL, to notify
Helgrind that it can forget about any h-b edges previously associated
with the specified tag, and release associated resources.

3cc6fcac8c Change the semantics of ANNOTATE_HAPPENS_BEFORE from 'overwrite' to 
'add' behaviour, w.r.t. any h-b edges associated with the
synchronisation object prior to the call.  This brings the behaviour
into line with DRD and TSan, and is required for correct annotation of
thread safe reference counting.  It fixes #243935 -- at least, the
original bug as discussed in comments 0 and 2.

the last lock in the list was never deleted.)

c9ed16792f Bring avg translation size statement closer to reality, for

soaks up so much space that a low-side of 320 seems prudent.
