    [maglev] Fix stack overflow issues · 4116937c
    Leszek Swirski authored
    Add a stack check to maglev function entry, and ensure that there is
    deopt info on the safepoint when there is a loop interrupt which can
    also stack check.
    
    These are somewhat hacky fixes for now, both of which do the minimal
    work to make OptimizedFrame::Summarize work. There are some TODOs on
    making this better, in particular not relying on lazy deopt info for
    said summarize. Cleaning this up will likely be part of a larger piece
    of work around exception support.
