- Add resolveUnionAlignment, to resolve a union's alignment only, without triggering layout resolution.
- Update resolveUnionLayout to cache size, alignment, and padding. abiSizeAdvanced and abiAlignmentAdvanced
now use this information instead of computing it each time.

As suggested by mlugg, always returns `error.NeedLazy`. If this has a
performance impact, it could be replaced by adding lazy handling to
`comptimeOnlyAdvanced`.
This commit starts by making Zir.Inst.Index a nonexhaustive enum rather
than a u32 alias for type safety purposes, and the rest of the changes
are needed to get everything compiling again.
This field had the wrong type. It's not a `Zir.Inst.Index`, it's
actually a `Zir.OptionalExtraIndex`. Also, the former is currently
aliased to `u32` while the latter is a nonexhaustive enum that gives us
more type checking.
This commit is preparation for making this field non-optional. Now it
can be changed to `Zir.ExtraIndex` and then the compiler will point out
all the places that the non-optional assumption is being violated.
The main motivating change here is to prevent the creation of a fake
Decl object by the frontend in order to `@export()` a value.
Instead, `link.updateDeclExports` is renamed to `link.updateExports` and
accepts a tagged union which can be either a Decl.Index or a
InternPool.Index.
The main problem being fixed here is there was a getOrPut() that held on
to a reference to the value pointer too long, and meanwhile the call to
`lowerConst` ended up being recursive and mutating the hash map,
invoking undefined behavior.
