This allows us to roll the Parser back to an earlier state if we need
to do so. This includes:
- rewinding the lexer
- restoring the previous Pushback node
- backing out AST nodes
- backing out errors
This functionality is used to back out of parsing a vardecl if we
discover mid-stream that it is actually an expression statement that
coincidentally starts with the name of a type.

Replace "pathToTriangles" with "pathToPolys, polysToTriangles". This
will allow the tessellator to do pathToPolys in onPrePrepare and
polysToTriangles in onPrepare.
Don't make countPoints and polysToTriangles virtual. This is a step
toward moving the outer mesh of GrAATriangulator back out of the
class, which seems to match the style better.

The basic problem was that WasmContextInfo shadowed non-virtual members
of ContextInfo. the tests, which work with that type, end up calling the
super class's methods which return null for directContext()
The context created and stored in WasmContextInfo would have worked if it
could be returned, but I've opted to go with what looks like a more
canonical way to test a new backend, that is to create a platform-
specific subclass of GLTestContext, and let GrContextFactory create the
GL context.

I wrote this looking for places where we treat w differently from z.
None of these are an urgent problem today, but 2) could become one, and
all good to fix if only for consistency.
1) Recycle w's register when it dies in the interpreter.
If we don't recycle w's register slot when w dies, we'll keep
thinking w's alive and keep that slot around in case it's used.
This is only an inefficiency, but nice to avoid when we can.
2) Don't allow spilling w when looking for an unused register.
This is a JIT bug fix, avoiding the possibility of clobbering w with
dst(),x,y,z or a temporary when we need to use it. Doesn't look like
it's happening today, but could sneak in.
3) Allow aliasing w and dst().
This is for completeness, moot today... store128 is the only op using
w and doesn't use dst(), let alone try to alias them.

This isn't really how I intended to use these, but we might as well
check if the registers happen to already be lined up how we'd like them.
And it happens quite often... I didn't gather detailed numbers, but both
sides of the "are we lined up?" conditions are being hit lots and lots
of times, in both store64 and store128.
Also rewrote the scalar flow of store128 to mirror store64. The old
code was just fine, but this makes it easier to follow the conditions of
when we can use st4. (This does remind me that we could also use
single-lane st2/st4/ld2/ld4 instructions to handle the scalar paths.)

The previous implementation assumed that SkSL expressions do not have
side effects and so treated either side of a Boolean expression as
short-circuitable. That is, `foo() && false` and `false && foo()` would
both be optimized to `false`, eliminating the `foo()` call.
We now check for side effects first. An expression like `expr && false`
can only be optimized to `false` if `expr` has no side effects. (If
`expr` does have side effects, the expression is left as-is.)
