I think this actually turns the code in question into dead code, because the current definition of UseSparseVariant only allows arrays in DictionaryMode, and these never return encoded ranges from %GetArrayKeys. This is a subtle link between the definition of %GetArrayKeys and UseSparseVariant, so I would prefer to keep the code rather than having an invisible depeendency.

The existing version does not have a correct implementation of Generate_OnStackReplacement since we do not correctly find the loop depth. This is mainly because EmitStackCheck in full-codegen-x64.cc did not write it and partly due to us reading at the wrong offset (which had no effect when it was not written in the first place, we simply got a random number from the next instruction). The DoComputeOsrOoutputFrame is very similar to the ia32 version.

We can wrongly assume that exception which is not intended to be caught by external try/catch should be caught if this exception inherits external catcher from some previous exception. To prevent that, clear external catcher when processing exceptions which cannot be externally caught.

Allocate the context in the prologue. Two issues had to be solved: (1) deoptimization needs to handle functions with a local context, (2) we need a safepoint in the prologue. (Thanks to Kevin.)

The main issue was due to multiple recompilations of functions. Now code objects are grouped by function using SFI object address. JSFunction objects are no longer tracked, instead we track SFI object moves. To pick a correct code version, we now sample return addresses instead of JSFunction addresses. tools/{linux|mac|windows}-tickprocessor scripts differentiate between code optimization states for the same function (using * and ~ prefixes introduced earlier). DevTools CPU profiler treats all variants of function code as a single function. ll_prof treats each optimized variant as a separate entry, because it can disassemble each one of them. tickprocessor.py not updated -- it is deprecated and will be removed.

Add more generic version of reloc info padding to ensure enough space for reloc patching during deoptimization (fixes issue 1174). The old version only added extra space when we did indirect calls, but the problem remains the same with normal calls that can be represented as a single byte. When doing patching each call will always be at least 2 bytes long because we use RUNTIME_ENTY as the reloc mode.
