This CL implements a naive tiering-up strategy where the interpreter
is used for the first execution for every regex, and the compiler is
used for every execution after that. The only exception is if a
global replace is being executed on a regex, we eagerly tier-up to
native code right away.
To use the tier-up logic --regexp-tier-up needs to be set. It is
currently disabled by default.

Per the July TC39 meeting consensus, we'd like to make the
upcoming String.prototype.replaceAll proposal throw for
non-global RegExp searchValues. However,
String.prototype.matchAll currently does not throw in this
case, causing consistency concerns.
This patch adds a use counter for String.prototype.matchAll
with a non-global RegExp as the searchValue. Hopefully, this
pattern isn't too common in real-world code today, in which case
we can both a) change matchAll and b) proceed with the desired
replaceAll semantics.

This class used to be based on DispatchTable, which itself uses an
interval tree to both categorize and canonicalize ranges
(i.e. such that no overlap and all immediately adjacent ranges are
merged). The produced ranges were then entered into lists for
{bmp,lead_surrogate,trail_surrogate,non_bmp} splits.
With this CL, we simplify to a plain loop over all character range
kinds instead. The dispatch table (and ZoneSplayList, perhaps
SplayList) can be removed in follow-ups.

* Set RegExpImpl methods private if possible (these will later be

* Merge RegExpEngine::CompilationResult into RegExpCompileData.
* Move remaining RegExpEngine methods to RegExpImpl and delete
RegExpEngine.
* Extract RegExpGlobalCache.
* Document a few data structures.
Upcoming CLs will rename RegExpImpl to RegExp and jsregexp.h to
regexp.h. This should then be the only header included from other

RegExp assertions (e.g.: '^', '$', '\b', ...) sequences have certain
properties that this rewriter exploits:
1. They are zero-width and order-independent, thus one can remove all
duplicate assertions.
2. If a subsequence is guaranteed to fail, the entire sequence fails.
Any sequence always known to fail (e.g. containing both '\b' and '\B')
can be rewritten to a single node that triggers failure.
This CL generalizes the previous optimization for repeated assertions
to be order-independent, i.e. assertions only have to be in the same
sequence but not next to each other.

The platform specific macro assembler headers can not be included
directly. They require symbols declared in macro-assembler.h.
We also cannot include macro-assembler.h from the platform specific
headers, because that would form a cycle, and the include in
macro-assembler.h would be skipped, which then also fails.
This CL documents and enforces this unfortunate situation.
This helps with further iwyu cleanups.
Note that current code which includes the platform specific headers
only works because we transitively included macro-assembler.h already
before.

Moves the unicode predicate cache tables out of the unicode cache,
and turns them into generic predicates in char-predicates.h which
use static constexpr tables.
This drops the per-isolate cost of unicode caches, and removes the
need for accessing the unicode cache from most files. It does remove
the mutability of the cache, which means that there may be regressions
when parsing non-ASCII identifiers. Most likely the benefits to ASCII
identifiers/keywords will outweigh any non-ASCII costs.

"short" external strings are not short, they mean that the external data
pointer is not cached. Rename the various classes and objects to align
with the actual meaning.

The "Address" type is V8's general-purpose type for manipulating memory
addresses. Per the C++ spec, pointer arithmetic and pointer comparisons
are undefined behavior except within the same array; since we generally
don't operate within a C++ array, our general-purpose type shouldn't be
a pointer type.

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.

This CL fixes all occurences that don't require special OWNER reviews,
or can be reviewed by Michi.
After this one, we should be able to reenable the readability/check

New code should use nullptr instead of NULL.
This patch updates existing use of NULL to nullptr where applicable,
making the code base more consistent.

- Move things to conversions.cc that don't need to be in headers
- Turn InternalStringToInt into a subclassable helper class
so we can re-use it for BigInt.parseInt
- Bonus: play a round of IWYU with all the .cc files who thought that
#including conversions-inl.h would give them nice Unicode things
