New Revision: fcbdc2072d

Log:
Dynamically derive base_label in iseq
base_label isn't used very often in iseq and we can dynamically derive it
from the label (of the current iseq or the local_iseq). We can remove this
field to save 8 bytes.
Modified files:
compile.c
iseq.c
vm_backtrace.c
vm_core.h
vm_insnhelper.c
zjit/src/cruby_bindings.inc.rs
