aaf6340eb3 Fixed two register allocator bugs (off-by-one error/failure propagation). 
Minor cleanups on the way, e.g. making sure that we never use something after an allocation failed. Style question: Should we switch to some kind of MUST_USE_RESULT-style to ensure that we handle failures consistently? Not sure...

1afc70a332 Fix huge heap snapshot when a heavily shared context has many variables 
Prevously v8 put a link to each context variable into a function where
the variable is visible.
Because of that if there are N functions sharing a context having M variables
then N*M links were created for the snapshot.
The fix makes v8 to put the links into the context object.

9be937e6ed 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.

This unifies the translation of a compiled stub frame to a stub failure
