MIPS: fix NaN handling of Isolate::StackOverflow()
...
The mjsunit/stack-traces-overflow.js test fails on MIPS target as Error.stackTraceLimit = NaN; should disable stack trace messages and Isolate::StackOverflow() assumes static_cast<int>(double NaN) < 0.
MIPS has a different NaN representation than other architectures so the NaN value casted to int is positive. This patch adds an isnan() check to make the handling of NaN uniform on all architectures.

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).

Avoid handle dereference during graph optimization.
...
With parallel recompilation enabled, objects made accessible by handles may
have changed between graph construction and graph optimization. Therefore
we must not assume that information on those objects remain the same between
those two phases. To police this, we forbid handle dereferencing during
graph optimization.
Exceptions to this rule are:
- Dereferencing the handle to obtain the raw location of the object. This
is safe since parallel recompilation acquires RelocationLock
- Some places that dereference the handle for a type check. These are checked
to be safe on a case-by-case basis.

termination exception so that the engine can continue to be used.
* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
exception, HasTerminated() will return true to indicate it is valid to
call V8::ResumeExecution() if desired.
A test case is added to cctest/test-thread-termination.cc.
