      [heap] Relax accessing markbits in ranges. · b152bb75
      Pierre Langlois authored
      When calling the `bitmap(chunk)` method of the various *MarkingState accessors
      we would receive a raw `Bitmap` pointer which does not tell you if accesses to
      markbits should be made atomically or not. As a result, we would default to
      doing atomic operation when in fact it may not be necessary.
      
      Here we're introducing a templated `ConcurrentBitmap` class that wraps
      operations done on the markbits and allows them to be made non-atomic.
      
      Additionaly, some of the `Bitmap` methods were only used to verify the heap and
      in the tests so they do not need atomic implementations. Using them in a
      concurrent context should now fail to link to make sure they're not mis-used in
      the future.

      Normalize casing of hexadecimal digits · 822be9b2
      Mathias Bynens authored
      This patch normalizes the casing of hexadecimal digits in escape
      sequences of the form `\xNN` and integer literals of the form
      `0xNNNN`.
      
      Previously, the V8 code base used an inconsistent mixture of uppercase
      and lowercase.
      
      Google’s C++ style guide uses uppercase in its examples:
      https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters
      
      Moreover, uppercase letters more clearly stand out from the lowercase
      `x` (or `u`) characters at the start, as well as lowercase letters
      elsewhere in strings.
