Makes LogicalNot bytecode not do the ToBoolean operation, and add support in the
peephole optimizer to choose between the appropriate bytecode depending upon
whether the previous bytecode emitted a boolean or not.

Revert of [Interpreter] Remove InterpreterExitTrampoline and replace with returning to the entry trampoline. (patchset #6 id:170001 of https://codereview.chromium.org/1969423002/ )

Reason for revert:

This changes the parser to keep around bodies for asm.js functions when
then asm.js validator is turned on. Eventually the validator will work
on one function at a time, but for now we validate the entire module at
once.

Original Commit Messag:
  This adds back the instanceof operator support in the backends and
  introduces a @@hasInstance protector cell on the isolate that guards the
  fast path for the InstanceOfStub. This way we recover the ~10%
  regression on Octane EarleyBoyer in Crankshaft and greatly improve
  TurboFan and Ignition performance of instanceof.

In order to support compiling to baseline on return we need to be able to
return to the actual return address. With this change this is what the
Return bytecode now does, removing the need for the
InterpreterExitTrampoline.

This change also removes the InterpreterNotifyDeoptXXX builtins and
unifies FCG and Igntion to both use NotifyDeoptXXX. As part of this
change, FullCodegenerator::State is moved to Deoptimize::BailoutState.

This makes escape analysis treat all guard nodes in the graph as an

just serves as a temporary workaround to get things going.

This commit introduces a new mode for bytecode_dispatches_report.py
which reports the top sources of dispatches to a given bytecode and
the top destinations of dispatches from the same bytecode.

The bytecode name is passed with --top-dispatches-for-bytecode
(short form: -f), while the number of sources and destinations to
show is controlled with -n.

Contrary to AstVisitor, which does not implement any traversal logic,
AstTraversalVisitor provides default implementations for each Visit*
function which walk through the AST. It is intended to be used as a base
class for visitors which are only interested in a small portion of the
AST.

Trying to reland http://crrev.com/1974293002.

This time some blocks have been shuffled around in the AddStub so that the frame still doesn't get built for the fast path.

Also disables the DCHECK(!is_default_snapshot) in snapshot-common.cc if --debug-code is specified. This was causing cctest to fail on arm64 debug builds.

RegExp.prototype.compile does not mutate it. This patch changes

Ordinary arrow functions have 'undefined' in their frame's receiver.
Generators restore the receiver to the frame based on one passed in
when they are constructed in CreateJSGeneratorObject.

This patch makes async arrow functions pass in 'undefined' for their
receiver so that they have the same behavior as ordinary arrow
functions, which avoids the issue of encountering TDZ when calling
an async arrow function in a subclass constructor before a super
call has returned.
