I can't reproduce any of these flakes anymore on windows or linux. Some are confirmed fixed with the same root cause as crbug.com/v8/8883. Others are not reproducible anymore and were probably fixed by other de-flaking and bugfixes in the last 6 months.

We somehow forgot to thread through the VectorSlotPair for the CALL_IC based speculation feedback to CheckedTaggedToTaggedPointer. This was showing for example with `String#concat()` where we ended up with an endless deoptimization loop if the parameter was a Smi.

The logic for removing while iterating is non-standard and a left over from a previous index based loop. This patch replaces it with a standard erase based version. This fixes a runtime crash with MSVC that invalidates the iterator and then asserts. This also makes the code safe in case the last move can be redundant.

GetSymbol previously always internalized the underlying string, even if the preparser does not need it. The most common case where this isn't needed is property name parsing. This seems to speed up preparsing quite a bit. For future reference: Property names in object literals still are needed due to various checks (e.g., get 'constructor', duplicate __proto__, ...); as well as cover grammar parsing (property names can turn into variable references). If we turn all strings that the preparser needs to identify back into contextual keywords we may be able to avoid the former.

This CL introduces a new expression that can replace "std::string" fields in other expressions. The main goal is to get SourcePositions for identifiers to make them available in the language server. The CL introduces a separate symbol "name", that allows to incrementellay replace strings with name expression where needed. As an example, variable delcarations now use a NameExpression for the variable name.

By making EmptyIdentifierString (used for failure-mode parsing) point to the empty_string() we can drop nullptr checks in the preparser. This is similar to what the parser already does.
