Improved code generation infrastructure by doing simple register allocation and constant folding and propagation.
Optimized regular expression matching by avoiding to create intermediate string arrays and by flattening nested array representations of RegExp data.
Traverse a few stack frames when recording profiler samples to include partial call graphs in the profiling output.
Added support for using OProfile to profile generated code.
Added remote debugging support to the D8 developer shell.
Optimized creation of nested literals like JSON objects.
Fixed a bug in garbage collecting unused maps and turned it on by default (--collect-maps).
Added support for running tests under Valgrind.
