Julian Seward 75fd9878c9 Merge (from branches/THRCHECK) the following amd64-linux stack unwind ...

kludges^H^H^H^H^H^H^Henhancements:

r6802: For VG_(record_ExeContext) et al, add a new parameter
(first_ip_delta) which is added to the initial IP value before the
stack is unwound.  A safe value to pass is zero, which causes the
existing behaviour to be unchanged.  This is a kludge needed to work
around the incomplete amd64 stack unwind info in glibc-2.5's clone()
routine.

r7059: Add a last-ditch heuristic-hack to the amd64-linux stack
unwinder, which is used when all other methods fail.  Seems like GDB
has something similar.
