This adds an additional column with percentages to the output of
bytecode_dispatch_report.py --top-dispatches-for-bytecode.
The percentages always represent the relative number of dispatches to
the target bytecode to all dispatches from the source bytecode.
The additional flag --sort-sources-relative/-r allows sorting the
"Top sources of dispatches to" the given bytecode by this column to more
easily find bytecodes that significantly often dispatch to the target.

Revert of [Interpreter] Collect type feedback for 'new' in the bytecode handler (patchset #6 id:100001 of https://codereview.chromium.org/2153433002/ )

Reason for revert:
This cl causes a large regression in octane (https://chromeperf.appspot.com/group_report?bug_id=629503). I have to investigate the reason before I can reland this.

Instead of wriring the elements kind transitions into the control flow
early on, we do instead put this marker into the effect chain, so that
the elements transitions are visible to the LoadElimination and can
thus be optimized properly there.

This CL itself doesn't add any of those optimizations, but just adds
the foundations to make them possible later.

Eagerly set arguments_, new_target_ and ths_function_ Scope, and unset if we don't need to allocate them.

This probably slightly speeds up AllocateParameterLocals, but more importantly it removes ast_value_factory_ uses. If we get rid of ast_value_factory from Scope it's easier to lazily allocate it later from within a ScopeState object.

Calling Runtime::kAbort through a builtin instead of the c-entry stub
will allow to generate the call in a background thread, because a
builtin provides its own handle, whereas a code stub does not.

This allows to pass deoptimization reasons to the profiler without the
requirement of always providing a source position. The absence of deopt
reasons is now communicated via a sentinel as the deopt id value. The

Introduce a proper CodeStubAssembler::BranchIfToBooleanIsTrue helper
method, that branches to if_true/if_false labels depending on whether
the value that is passed would yield true or false when fed to
ToBoolean. Use this helper to implement the bytecode handlers w/o having
to materialize the temporary booleans and essentially branching twice.
The CodeStubAssembler::BranchIfToBooleanIsTrue helper favors the most
likely case of a Boolean constant now.

Also migrate the ToBooleanStub to a ToBoolean TurboFan builtin, that
also uses the helper method under the hood.

Remove the now obsolete Oddball::to_boolean field.
