c4224f09a2 Notify CPU profiler when calling native getters 
This change modifies code produced by BaseLoadStubCompiler::GenerateLoadCallback so that instead of calling AccessorGetter direcly it calls InvokeAccessorGetter which changes VM state and calls the actual callback. This way CPU profiler knows which external callback is being executed in this case. Indirect call happens only if CpuProfiler::is_profiling() is true.

This is exactly same change as r15116 with a build fix for test-api.cc

e4edbb0535 Cleaned up CpuFeature scope handling. 
First of all, it has nothing to do with Isolates, it is related to the assembler
at hand. Furthermore, the saving/restoring is platform-independent. Cleaned up
some platform-specific stuff on the way.

Note that there are some things which still need some cleanup, like e.g. using
EnumSet instead of uint64_t, making Probe() more uniform across platforms etc.,
but the CL is already big enough.

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.

be8e8f7528 Improve the JitCodeEventHandler API to add support for line position information. 
This includes:

* adding the CODE_ADD_LINE_POS_INFO, CODE_START_LINE_INFO_RECORDING, CODE_END_LINE_INFO_RECORDING event and the corresponding functionality.
 * adding the JITCodeLineInfo struct to record the code line info. I added this definition because Danno mentioned that "we'd like to cleanup and decouple the external debugging functionality"
 * some other small changes.

bd4e114b8e Add code again to allow reclaiming old unexecuted functions. 
When code objects in the heap for FUNCTIONs and OPTIMIZED_FUNCTIONs are marked by the GC, their prologue is patched with a call to a stub that removes the patch. This allows the collector to quickly identify code objects that haven't been executed since the last full collection (they are the ones that sill contain the patch). The functionality is currently disabled, but can be activated by specifying the "--age-code".
