Revert of Deactivate Parser Bookmarks (patchset #1 id:1 of https://codereview.chromium.org/1315173007/ ) Reason for revert: Tanks performance (Mandreel latency). A simple deactivation will not work.

port fbad6366 (r30467) original commit message: The call protocol requires that the register dedicated to the number of actual arguments (i.e. rax on x64) always contains the actual arguments. That means after adapting arguments it should match the number of expected arguments. But currently we pass some semi-random value (usually some stack address) after adapting arguments. It looks like this is currently not observable anywhere, because our builtins and functions either don't look at the number of arguments and just make hard coded (unchecked) assumptions, or are marked as "don't adapt arguments", which bypasses the broken code in the trampoline for arguments adaption. Nevertheless this should be fixed. BUG= Review URL: https://codereview.chromium.org/1304893010 Cr-Commit-Position: refs/heads/master@{#30605}

The original intention of this seemed to have been to enable DEBUG when NDEBUG was not defined within Google3.

Once a range is found to have a conflict, split around all the calls it crosses over, since it will anyway have conflicts there, too. Incrementally, from the last change to greedy, this change brings overall improvement in benchmarks. In fact, except for 2 regressions in Jetstream (splay-latency and date-format-xparb, at 6 and 7% respectivelly), everything else is in the green or noise. Quite a few benchmarks are over 3%, with a few (zlib, for example) in the double digits. Review URL: https://codereview.chromium.org/1328783002 Cr-Commit-Position: refs/heads/master@{#30579}

Also remove the (unused) premature %_GetPrototype optimization from Crankshaft, which just complicated the Map bit swap.
