      [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.
