91b897ef58 rework memory management of Module.Namespace hash maps 
The motivating problem here was a memory leak in the hash maps of
Module.Namespace.

The commit deletes more of the legacy incremental compilation
implementation. It had things like use of orderedRemove and trying to do
too much OOP-style creation and deletion of objects.

Instead, this commit iterates over all the namespaces on Module deinit
and calls deinit on the hash map fields. This logic is much simpler to
reason about.

Similarly, change global inline assembly to an array hash map since
iterating over the values is a primary use of it, and clean up the
remaining values on Module deinit, solving another memory leak.

After this there are no more memory leaks remaining when using the
x86 backend in a libc-less compiler.

70d8baaec1 Revert "Sema: fix comparison with undefined" 
This reverts commit 547481c31c8a538a7badbdce66d81820177ce87f.

There is a comment that did not get addressed with this patch, and the
required test cases are not added.

Reopens #17798.

7048e93665 Package.Fetch.git: handle optional pkt-line LF 
Addresses a comment in #17779 pointing out the inability to fetch the
upstream BoringSSL sources over Git. The reason for this is because the
Git server used in this case did not include the optional (but
recommended) LF terminator for textual pkt-line data. This commit
adjusts handling of textual pkt-line data so that it works both with and
without the optional trailing LF.

d93f1f3c72 Sema: detect unneeded source locations earlier 
This avoids a lot of work that just needs deferred cleanup anyway.
Crucially, also avoids use of undefined in `failWithNeededComptime`.

0f2489d8fc macho: resolve special section/segment boundary symbols 
Boundary symbols have a special name prefix:

* section$start$segname$sectname
* section$stop$segname$sectname
* segment$start$segname
* segment$stop$segname

and will resolve to either start or end of the respective
section/segment if found.

If not found, we return an error stating we couldn't find the
requested section/segment rather than silently failing and resolving
the address to 0 which seems to be the case with Apple's ld64.
