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.
