The counting loop is always run at least once, and checking the loop condition once is sufficient.

We do not currently check that a global property is actually
configurable before overwriting it with a new property.

The current version includes an extra jump compared to IA32, because
we need to load the jump address into a register and do an indirect
jump, but in the normal case we just jump over this by negating the
deoptimization conditional.

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.

Since writting a code comment can include a pc-jump the assertion
