[deoptimizer] Remove uses of TranslationIterator outside the deoptimizer.

[deoptimizer] Remove uses of TranslationIterator outside the deoptimizer.

Use the new TranslatedState and friends, which work at a higher level
than the TranslationIterator, which will make it easier to change the
deoptimization commands in subsequent CLs.

Hey Jaro,

This is preliminary cleanup for the deoptimizer. Please take a look.

Thanks,
Benedikt

lgtm.

File src/frames.cc (right):

https://codereview.chromium.org/1166353004/diff/1/src/frames.cc#newcode889
src/frames.cc:889: TranslatedState state(this);
I am wondering whether we should put this in no-allocation scope (or call
Prepare on the state to handlify). GC at this point would be bad.
