621e89a863 add bootstrap.c for building from source without LLVM 
When a zig compiler without LLVM extensions is satisfactory, this
greatly simplified build-from-source process can be used.

This could be useful for users who only want to contribute to the
standard library, for example.

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`.

138a35df8f zstandard: fix division by zero when using RingBuffer 
This change fixes some division-by-zero bugs introduced by the optimized
ring buffer read/write functions in d8c067966.

There are edge cases where decompression can use a length zero ring
buffer as the size of the ring buffer used is exactly the the window
size specified by a Zstandard frame, and this can be zero. Switching
away from loops to mem copies means that we need to ensure ring buffers
do not have length zero ring when attempting to read/write from them.

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.
