    [compiler] Cache OSR optimized code · cfb10028
    Mythri A authored
    With lazy feedback allocation, for functions that get OSRed we may
    not have feedback for the initial part of the functions since feedback
    vectors might be allocated after the function started executing. Hence
    we would not be able to optimize the function on the next call. This
    means we may have to OSR twice before we actually optimize function.
    This cl introduces OSR cache, so we could reuse the optimized code. One
    side effect of this cl is that the OSRed code won't be function context
    specialized anymore.
