      [regexp] Fix non-unicode ignore-case backreferences · b65fcfe9
      Iain Ireland authored 
      https://crrev.com/c/2072858 rewrote the implementation of non-unicode
ignore-case matches to comply with the JS spec in some corner
cases. It fixed character matches and character class matches.

We missed a similar bug in the implementation of back references. This
CL fixes that bug.

The main change is in regexp-macro-assembler.cc, where
CaseInsensitiveCompareUC16 is split into CaseInsensitiveCompareUnicode
(which has the same semantics as before) and
CaseInsensitiveCompareNonUnicode (which has the semantics described
here: https://tc39.es/ecma262/#sec-runtime-semantics-canonicalize-ch).

Most of the rest of the patch undoes https://crrev.com/c/2081816 to
once again make the unicode flag available to the macroassembler, so
that we can decide which helper function to call.

The testcase is a version of test/intl/regress-10248.js, modified to
test backreferences.

      [snapshot] Clear reconstructable data prior to d8 stress_snapshot run · 3c422d1c
      Jakob Gruber authored 
      The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the
--stress-snapshot d8 flag, we clear compiled data from the isolate
prior to the serialize-deserialize-verify pass.

With this change, mjsunit tests pass on x64.

The %SerializeDeserializeNow() runtime function would require more
work, since it is not possible to mutate the heap to this extent while
still preserving a runnable host context and isolate. We will need
another solution there.

Drive-by: Skip the stress_snapshot variant except for the mjsunit
suite.

      [regexp] Fix and unify non-unicode case-folding algorithms · 3fab9d05
      Iain Ireland authored 
      Non-unicode, case-insensitive regexps (e.g. /foo/i, not foo/iu) use a
case-folding algorithm that doesn't quite match the Unicode
definition. There are two places in irregexp that need to do
case-folding. Prior to this patch, neither of them quite matched the
spec (https://tc39.es/ecma262/#sec-runtime-semantics-canonicalize-ch).

This patch implements the "Canonicalize" algorithm in
src/regexp/special-case.h, and uses it in the relevant places. It
replaces special-case logic around upper-casing / ASCII characters
with the following approach:

1. For most characters, calling UnicodeSet::closeOver on a set
   containing that character will produce the correct set of
   case-insensitive matches.

2. For a small handful of characters (like the sharp S that prompted
   this change), UnicodeSet::closeOver will include some characters
   that should be omitted. For example, although closeOver('ß') =
   "ßẞ", uppercase('ß') is "SS", so step 3.e means that 'ß'
   canonicalizes to itself, and should not match 'ẞ'. In these cases,
   we can skip the closeOver entirely, because it will never add an
   equivalent character. These characters are in the IgnoreSet.

3. For an even smaller handful of characters, UnicodeSet::closeOver
   will produce some characters that should be omitted, but also some
   characters that should be included. For example, closeOver('k') =
   "kKK" (lowercase k, uppercase K, U+212A KELVIN SIGN), but KELVIN
   SIGN should not match either of the other two (step 3.g). To handle
   this, we put such characters in the SpecialAddSet. In these cases,
   we closeOver the original character, but filter out the results
   that do not have the same canonical value.

The computation of IgnoreSet and SpecialAddSet happens at build time,
using the pre-existing gen-regexp-special-case.cc step.
