Philippe Waroquiers 619fb35df7 Fix 376257 - helgrind history full speed up using a cached stack ...

This patch implements the flag --delta-stacktrace=yes/no.
Yes indicates to calculate the full history stack traces by
changing just the last frame if no call/return instruction was
executed.
This can speed up helgrind by up to 25%.

This flags is currently set to yes only on linux x86 and amd64, as some
platform dependent validation of the used heuristics is needed before
setting the default to yes on a platform. See function check_cached_rcec_ok
in libhb_core.c for more details about how to validate/check the behaviour
on a new platform.
