Distinguish between GC disabled by BIFs and other disabled GC
Processes remember heap fragments that are known to be fully live due to creation in a just called BIF that yields in the live_hf_end field. This field must not be used if we have not disabled GC in a BIF. F_DELAY_GC has been introduced in order to distinguish between to two different scenarios. - F_DISABLE_GC should *only* be used by BIFs. This when the BIF needs to yield while preventig a GC. - F_DELAY_GC should only be used when GC is temporarily disabled while the process is scheduled. A process must not be scheduled out while F_DELAY_GC is set.
