Chris Tate a48464a1a6 Inspect self-referential error subclasses without recursing; render their cycles as Node does

fieldedErrorReason checked each field of a fielded error class with a
fresh inspectSupport walk, so a field typed as the class itself
(`next: Chain`) recursed until the compiler's stack overflowed. It now
continues the caller's walk, where the class is a recursive shape.

The fielded error helper then rendered a cycle by expanding it to the
depth budget, where Node prints `<ref *1>` and `[Circular *1]`. Classes
whose fields reach the class or one of its bases now run the circular
machinery other cycle-capable objects use (circCheck before the depth
answer, seenPush, refWrap), which also covers a cycle through a
base-typed field of a subclass. New corpus program
6526-error-subclass-cycles.ts.

6187-js-match-or-empty-array.js compiles without its deferred fence now
that the match-or-empty union reads through its widened members: the
`@deferred-fences: 1` header goes, and the program calls the function
the fence used to cover.
