Instead of checking for stage1 at every callsite, move the logic
inside `allocateAtom`. This is fine since this logic will disappear
anyhow once I add expanding and shifting segments and sections.
There was some new code in master branch enumerating all the targets and
a new target was added so we needed to add the glue code.
This commit also introduces some build options to support experimental
LLVM targets.
This commit makes it possible to combine self-hosted with a pre-compiled
C object file, e.g.:
```
zig-out/bin/zig build-exe hello.zig add.o
```
where `add.o` is a pre-compiled C object file.
Also:
* improve the "ambiguous reference" error by swapping the order of
"declared here" and "also declared here" notes.
* improve the "not accessible from inner function" error:
- point out that it has to do with the thing being mutable
- eliminate the incorrect association with it being a function
- note where it crosses a namespace boundary
* struct field types are evaluated in a context that has the struct
namespace visible. Likewise with align expressions, linksection
expressions, enum tag values, and union/enum tag argument
expressions.

d57c0cc3bfeff9af297279759ec2b631e6d95140 added support for DragonFlyBSD
to libc++ by updating some ifdefs. This needed to be synced with llvm13.
* stage2 AstGen: add missing compile error for declaring a local
that shadows a primitive. Even with `@""` syntax, it may not have
the same name as a primitive.
* stage2 AstGen: add a compile error for a global declaration
whose name matches a primitive. However it is allowed when using
`@""` syntax.
* stage1: delete all "declaration shadows primitive" compile errors
because they are now handled by stage2 AstGen.
* stage1/stage2 AstGen: notice when using `@""` syntax and:
- treat `_` as a regular identifier
- skip checking if an identifire is a primitive
Check the new test cases for clarifications on semantics.

This way, we will conform to the standard practice of setting the
offset within the section header to the beginning of the file and
we will be able to track the location of the section in the file
for incremental updates.
* rework `build_options` to integrate with the FileSource abstraction
* support mapping as an arbitrarily named package
* support mapping to multiple different artifacts
* use hash of contents for options filename
