Adds support for zone allocated (off-heap) ConsumedPreParsingScopeData to
enable worker-thread access to PreParsingScopeData during parallel IIFE
compile tasks.
In order to avoid code-duplication, a templated
BaseConsumedPreParsingScopeData is added which implements the logic for
decoding the bytestream into scope data. Two implementations of this
base class are instantiated for each of the underlying serialized scope date:
- ZoneConsumedPreParsedScopeData for exposing ZonePreParsedScopeData
- OnHeapConsumedPreParsedScopeData for exposing on-heap PreParsedScopeData
The interface for each of these classes is the ConsumedPreParsingScopeData,
which exposes the methods required by the parser to deserialize the required
data.
As a side-cleanup, moved Ucs2CharLength and Utf8LengthHelper implementations
to cc file so that we don't get a linker error if one of them are unused by
the cc file including the header.

This reverts the following 3 CLs:
Revert "[scanner] Templatize scan functions by encoding"
Revert "[asm] Remove invalid static cast of character stream"
Revert "[scanner] Prepare CharacterStreams for specializing scanner and parser by character type"
The original idea behind this work was to avoid copying, converting and
buffering characters to be scanned by specializing the scanner functions. The
additional benefit was for scanner functions to have a bigger window over the
input. Even though we can get a pretty nice speedup from having a larger
window, in practice this rarely helps. The cost is a larger binary.
Since we can't eagerly convert utf8 to utf16 due to memory overhead, we'd also
need to have a specialized version of the scanner just for utf8. That's pretty
complex, and likely won't be better than simply bulk converting and buffering
utf8 as utf16.

This way we can avoid reencoding everything to utf16 (buffered) and avoid the
overhead of needing to check the encoding for each character individually.
This may result in a minor asm.js scanning regression due to one-byte tokens
possibly being more common.

This templatizes CharacterStream by char type, and makes them subclass ScannerStream.
Methods that are widely used by tests are marked virtual on ScannerStream and final on
CharacterStream<T> so the specialized scanner will know what to call. ParseInfo passes
around ScannerStream, but the scanner requires the explicit CharacterStream<T>. Since
AdvanceUntil is templatized by FunctionType, I couldn't mark that virtual; so instead
I adjusted those tests to operate directly on ucs2 (not utf8 since we'll drop that in
the future).
In the end no functionality was changed. Some calls became virtual in tests. This is
mainly just preparation.

Declare the private field variable in the preparser as well, to be
consistent with the parser.

Report an error during scope analysis if we're unable to find a
variable proxy for the given private field. This can happen if we try
to access a private field that was not defined or if we're outside
the class scope.
This doesn't correctly throw an early error when pre parsing a top
level function because we don't track it's variables.

This patch implements https://github.com/tc39/proposal-class-fields/pull/65
and https://github.com/tc39/proposal-static-class-features/ by
splitting out instance and static field declarations into separate
flags for the separate proposals. Instance class fields is currently
at Stage 3 whereas static class fields is currently at Stage 2.

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.

- Make it possible to store quarter-bytes instead of full bytes.
- Don't store is_used; it can be recovered correctly based on the actual full
parse (when a lazy function is eventually called) and
has_forced_scope_allocation.
- With the is_used change, the old testing approach (which compared a scope for
which we didn't do scope allocation to the baseline) no longer made
sense. Replaced it with a new testing approach, which is also closer to the
actual usage.
- First version (reverted): https://chromium-review.googlesource.com/725422
