Rationale:
catch (e) had a very interesting shadowing
with math's constant e, which unintentionally
allowed exeption text to enter the divergence
mechanism; here we were fuzzing the fuzzing
really :-)

The stack slot in question may contain a stale value, but it could
be scanned by GC, so the fix is to clean it up even if it looks
unused.
While debugging I saw bytecode PCs in that stack slot.
So it is likely that compact bytecode instructions (68de477535)
increased the probability of these crashes, as with compact bytecodes
PCs could be unaligned and treated as Dart objects by GC, while
previously PCs were always aligned and treated as Smis by GC,
effectively masking the failure.

This is the first of several CLs that move error tokens to the head
of the token stream so that parser handling of error tokens
can be simplified and less error prone.
In this particular CL:
- update parser to handle error tokens at the head of the token stream
- remove several places that analyzer was preprocessing error tokens
now that the parser handles them

There might be some false negatives, when there *is* another top-level
declaration with the same name as we are removing. But this is a
pre-existing conflict, so I think we should not be very concerned. At
some point we might collect initial potentially conflicting names using
the same SyntacticScopeNamesCollector instead of element model. With
element model we don't know about parser recovery.

In the long term this class will take over much of the role played by
RestrictedAnalysisContext. For now it is simply a container for the
analysis options, declared variables, type provider, and type system.
In follow-up CLs I will plumb this object through various parts of the
analyzer, especially the LinterContext; this will enable the
canBeConst... methods to be moved into SynchronousSession, and that
will allow us to stop creating a LinterContext in
BestPracticesVerifier.

document.registerElement is going away soon, and dart2js never implemented window.customElements.define.
Replace the inheritance with composition for each FooElement.
When used to create a DOM tree, replace `new FooElement()` with `new FooElement().element`.
In CSS, replace each custom element selector with a class selector, i.e. `foo-element` with `.foo-element`.
