Minor cleanups & trivial refactoring related to Ast.

1) Literal::IsNull, IsTrue and IsFalse were dead code, and not needed.
2) No need to use the node type constants outside the Ast; there is IsSomeNodeType().
3) AsSomeNodeType() != NULL -> IsSomeNodeType().

%ObjectFreeze needs to exclude non-fast-path objects.

ClusterFuzz will call it with sloppy arguments and similar cases.

Use full include paths everywhere

- this avoids using relative include paths which are forbidden by the style guide
- makes the code more readable since it's clear which header is meant
- allows for starting to use checkdeps

Fix PathTracer.

When tracing, we abuse the map for marking, thereby mutating it.
HeapObject::map() takes care of recovering unabused value.

Improve write barriers in optimized code.

Use a cheaper RecordWriteForMap() to update the
write barrier for maps. And skip the value check
in RecordWriteField() when we statically know that
the value is in new space (and therefore has "pointers
to here are interesting" flag set).
