* the root struct decl name is fully qualified
this prevents error messages containing 'main.main'
* avoid declared here note when file struct is missing a member
It always points at the start of the file which might contain another
container misleading the user.
The enum we want to get the fields from might not be declared in the
same file as the block we are analyzing, so we should get the AST from
the decl's file instead.
Closes#12950.
Many of these tests check for the incorrect behavior of stage1 whereas
self-hosted correctly does not emit an error, so they are simply
deleted.
The remaining number of test cases within the stage1/ subdirectory is
reduced from 143 to 103.
Storing defers this way has the benefits that the defer doesn't get
analyzed multiple times in AstGen, it takes up less space, and it
makes Sema aware of defers allowing for 'unreachable else prong'
error on error sets in generic code.
The disadvantage is that it is a bit more complex and errdefers with
payloads now emit a placeholder instruction (but those are rare).

Previously if a decl failed its capture scope would be deallocated and
set to undefined which would then lead to invalid dereference in
`zirClosureGet`. To avoid this set the capture scope to a special
failed state and fail the current decl with dependency failure if
the failed state is encountered in `zirClosureGet`.
