a0734ba3af Add deopt fuzzer tool. 
Can be run as a stand-alone script like run-tests.

Executes first all tests of a given test suite to collect the maximum number of possible deopt points. Runs then a fuzzing phase with artificial deoptimizations triggered during testing.

Works for now with mjsunit and ia32 only.

3cdeb2f9cd Avoid adding HWrapReceiver during graph building. 
This adds an early check to the graph builder which prevents adding an
HWrapReceiver instruction if the receiver type is already known at graph
building time. Also HAllocate no longer unnecessarily postpones setting
it's type until type inference but sets it right away. These changes are
in preparation for escape analysis.

97f8f91bb5 Fix call stack sampling for the case when native callback invokes JS function 
The SafeStackFrameIterator used by CPU profiler checked if Isolate::c_entry_fp is null and if it is not it would think that the control flow currently is in some native code. This assumption is wrong because the native code could have called a JS function but JSEntryStub would not reset c_entry_fp to NULL in that case. This CL adds a check in SafeStackFrameIterator::IsValidTop for the case when there is a JAVA_SCRIPT frame on top of EXIT frame.

Also this CL changes ExternalCallbackScope behavior to provide access to the whole stack of the scope objects instead of only top one. This allowed to provide exact callback names for those EXIT frames where external callbacks are called. Without this change it was possible only for the top most native call.

f59c36589d In MacroAssembler::JumpIfNotBothSequentialAsciiStrings a custom mask 
helps us decide if we have two ascii strings. We don't care if they
are internalized or not. A few days ago we flipped the meaning of the
internalized bit in INSTANCE_TYPE, and that broke this custom mask.
This CL effects a repair.
