6cc2b26163 sema: load the correct AST in addFieldErrNote 
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.

9f4408d68b organize some compile error tests 
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.

e323cf1264 stage2: change how defers are stored in Zir 
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).

99826a2ba8 Sema: fix UAF in zirClosureGet 
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`.

ae8d26a6a0 Sema: add error for non-comptime param in comptime func 
Adds error for taking a non comptime parameter in a function returning a
comptime-only type but not when that type is dependent on a parameter.

4405188cf7 Sema: ignore comptime params in partial func type check 
This fixes a bug exposed by cd1833044a
where a function type would be converted to generic_poison even after
being instantiated due to containing comptime only types.

This could also be fixed by just checking `is_generic_instantiation`
but this way also provides better type names.
