53310ac152 Added a version of the v8::HandleScope constructor with an Isolate and use that consistently. 
I tried to limit the use of v8::Isolate::GetCurrent() and v8::internal::Isolate::Current() as much as possible, but sometimes this would have involved restructuring tests quite a bit, which is better left for a separate CL.

55f93b5532 Renamed "symbols" to "internalized strings" throughout the code base, 
in preparation of the introduction of ES6 'symbols' (aka private/unique names).

The SymbolTable became the StringTable. I also made sure to adapt all comments. The only remaining use of the term "symbol" (other than unrelated uses in the parser and such) is now 'NewSymbol' in the API and the 'V8.KeyedLoadGenericSymbol' counter, changing which might break embedders.

The one functional change in this CL is that I removed the former 'empty_string' constant, since it is redundant given the 'empty_symbol' constant that we also had (and both were used inconsistently).

fb6776e84a Made Isolate a mandatory parameter for everything Handle-related. 
Unified parameter order of CreateHandle with the rest of v8 on the way. A few
Isolate::Current()s had to be introduced, which is not nice, and not every place
will win a beauty contest, but we can clean this up later easily in smaller steps.

8e7ae24b40 Fix disabling of code flusher while marking. 
This fixes a corner case when the code flusher is disabled while
incremental marking is running. The list of candidates needs to be
evicted to prevent list fragments without a head floating around.

03ba764f3e Put incremental code flushing behind a flag. 
This is used to disable incremental code flushing by default for now
until we can stabilize it and make it ready for production.

014f00fa51 Fix code flusher to process weak function links. 
This fixes a corner case where weak function links of the code flushing
candidates list were destroyed by scavenges that happened during
incremental marking. Now those weak function links are updated while
scavenging happens.

cee59bf522 Enable incremental code flushing. 
This enables code flushing even with incremental marking enabled and
fully shares the function link field in JSFunctions between candidates
for code flushing and the optimized functions list. If a candidate for
code flushing gets optimized, it will be evicted from the candidates
list.
