    [compiler] Mark HeapNumberRef as never serialized · 9905c0b3
    Mike Stanton authored
    This CL simplifies the approach to HeapNumbers in concurrent
    compilation. We'll only create a HeapNumberRef for immutable
    HeapNumbers -- this means that we don't need to validate the read
    of the value with a compilation dependency check. Mutable
    HeapNumbers are handled differently (the value is read for
    constant folding, and protected with a constant field dependency).
    
    This CL includes 2 reverts:
    Revert "[compiler] Make HeapNumberRef background serialized"
    Revert "[compiler] Fix endianness issue when reading HeapNumber"
