    [runtime] Speed up C++ version of ArrayPush · 2ae50119
    jkummerow authored
    Mostly by avoiding unnecessary Handle/HandleScope creation,
    "length" property lookups, and length conversions.
    This yields about 60% speedup on the microbenchmark I tested with.
    
    Note that the C++ builtin is the middle performance tier of three,
    so not every Array.push use case will be affected by this patch.
