machenbach 5bb6b47bd5 Revert of Non-pattern rewriting revisited (patchset #3 id:40001 of https://codereview.chromium.org/1702063002/ ) 
Reason for revert:
[Sheriff] This makes jsfunfuzz unhappy:
https://build.chromium.org/p/client.v8/builders/V8%20Fuzzer/builds/7681

Original issue's description:
> This patch implements an alternative approach to the rewriting
> of non-pattern expressions, according to the (internally circulated)
> design document.  Details to be provided here.
>
> 1.  RewritableAssignmentExpression has been renamed to RewritableExpression.
>     It is a wrapper for AST nodes that wait for some potential rewriting
>     (that may or may not happen).  Also, Is... and As... macros now see
>     through RewritableExpressions.
>
> 2.  The function state keeps a list of rewritable expressions that must be
>     rewritten only if they are used as non-pattern expressions.
>
> 3.  Expression classifiers are now templates, parameterized by parser
>     traits.  They keep some additional state: a pointer to the list of
>     non-pattern rewritable expressions.  It is important that expression
>     classifiers be used strictly in a stack fashion, from now on.
>
> 4.  The RewriteNonPattern function has been simplified.

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
