bsdinstall: Improve auto-partition message
Manually tuning ZFS for systems with <8GB ram hasn't been necessary at
least since the switch to OpenZFS. We have users reporting using 1GB RAM
with no manual tuning/issues. Further, the page this links to is a stale
wiki page, which is causing complaints. Remove this misleading note and
replace it with a similar message for UFS. While here, reword that note
to be a bit clearer.

ports.7/FILES: Expand and refactor into 3 tables
Add make.conf, CHANGES, CONTRIBUTING.Md, UPDATING, and Tools/scripts.
Refactor the FILES section of the ports reference manual into a bigger
table with three sections separated by root directory. Remove preceeding
article from all but "the big Kahuna", and root dirs where reasonable.

man: Kill off MANSUBDIRs
Three architecture dependent manuals are installed to MANSUBDIRs,
creating at least two empty manual page directories on everyone's
boxxen. Move those manuals to their canonical area, enhancing clarity,
grepability, removing useless inodes, and increasing consistency with
the rest of the architecture dependent manuals which are unconditionally
installed, and noted at the top of the rendered manual.

ahci: remove broken AHCI_COALESCE dead code
Remove the never-compiled AHCI Command Completion Coalescing
implementation. The code had multiple bugs (missing closing paren,
bare printf instead of device_printf, OpenBSD DEVNAME macro
incompatible with DragonFly newbus) and the approach is
fundamentally wrong for general-purpose I/O.
Hardware CCC delays every low queue-depth completion by the full
timeout value, destroying filesystem metadata latency on single
I/O operations that must wait for the coalescing window to expire.
Fix metadirective loop variant lowering
Preserve the associated DO evaluation when a dynamic metadirective can
select either a loop-associated directive or a standalone fallback, so
the fallback still lowers the original loop body.
Scope temporary loop-IV data-sharing attributes to the selected variant.
Use the selected variant's collapse clause to determine how many loop IVs
to mark, avoiding DSA state leaking between alternatives.
[PowerPC] Hardcode LDAT/LWAT_CSNE constant immediate (#196115)
The FC field in LDAT/LWAT_CSNE instructions is always 16, so hardcode it
in the TableGen definition instead of passing it as an explicit operand.
all: drop support for FreeBSD 13, mips and risc64sf

[flang][OpenMP] Support loop-associated metadirective variants (part 3)
Enable metadirective lowering for loop-associated variants such as
`do`, `simd`, `parallel do`, and `do simd`.
When a metadirective resolves to a loop-associated directive, the
sibling DO evaluation is spliced into the metadirective's evaluation
list so existing loop lowering finds it. Loop IV data-sharing
attributes are marked at lowering time since semantic analysis cannot
know which variant will be selected. The DataSharingProcessor is also
extended to handle spliced evaluations.
This patch is part of the feature work for #188820 and stacked on top
of #194424.

[NFCI][msan] Add test case for llvm.fptoui.sat/llvm.fptosi.sat (#196416)
Forked from llvm/test/Instrumentation/MemorySanitizer/ftrunc.ll
PR #191365 lowered NEON fcvtz[us] intrinsics into fpto[us]i.sat,
exposing a gap in MSan's instrumentation. A follow-up patch will add
support in MSan for ftop[us]i.sat, propagating the shadow (similar to
its handling of fcvtz[us]) rather than strictly handling them.
