    [parser] Inline byte scope data into PreparseData object · e2d44ede
    Camillo Bruni authored
    Each PreparseData object had at least one pointer to a PodArray for its
    serialized scope data. These objects usually have only tens of bytes of
    payload. By inlining the byte data we save 3 words per PreparseData object.
    This optimization saves 140KB of data on cnn.com.
    
    
    - Store data_length and inner_length as int32 saving a words on 64bit
    - Inline store byte data into PreparseData
    - OnHeapConsumedPreparseData directly uses the PreparseData object
    - get_inner, set_inner no longer allow Null sentinels
