[X86][GISel] Fix carry-in for selectUAddSub. (#199261)
When G_UADDE/G_USUBE was chained off a previous G_UADDE/G_UADDO/
G_USUBE/G_USUBO, selectUAddSub re-materialized EFLAGS.CF from the
previous SETB byte using CMP r, 1. That computes (r - 1) and sets
CF iff r < 1 unsigned, i.e. CF = (r == 0) -- the inverse of the
desired carry. The following ADC/SBB then consumed the wrong CF and
produced an off-by-one upper word; e.g. `add i128 0xFF..FF, 1` under
-global-isel returned hi=0 lo=0 instead of hi=1 lo=0.
Emit NEG r instead: NEG sets CF iff its operand is non-zero, matching
the SETB byte. NEG is a two-address (tied) instruction, so emit it
into a fresh virtual register rather than redefining the carry-in
vreg.
C reproducer (compile on x86_64-linux-gnu and run):
```
// clang -O2 -fglobal-isel repro.c -o repro && ./repro

tmpfs: Overhaul option handling on remount
On remount, we must accept all the same options as on initial mount.
For parameters which we're unable to modify on the fly, fail only if
the new value is different from the existing one.

tcp: Make RFC 6191 support configurable
Add a default-on per-VIMAGE sysctl for RFC 6191 connection recycling.
This makes it possible to merge the change to older branches where it
can be switched off by default to minimize risk.

pxeboot: warn and abort on TCP-only NFS server, which doesn't work for pxeboot
When pxeboot gets a 0 as a port number from portmapper (indicating an
error), it currently happily sends NFS packets to the server's port 0
in an endless loop. Change this to instead bail out with a useful
message.
This happens, for example, with recent Linux NFS servers as many
distributions switched to TCP only NFS serving by default. FreeBSD's
pxeboot must have UDP. In this situation pxeboot asks the server's
portmapper for the UDP NFS port and since there is none gets 0.
Also add a hint to the manpage explaining this and how to fix it.

evaluates an unprofitable ordered fadd reduction chain as profitable.

[libc][math] Implement isnanf16 header-only function (#198115)
Adds `isnanf16` the float16 variant of isnan as part of issue
[#195400](https://github.com/llvm/llvm-project/issues/195400), which
tracks adding missing isnan variants for extended floating-point types.
The implementation follows the same pattern as the existing `isnanf`,
`isnan`, and `isnanl` functions.

wasi/gecko: fix wasi target triple for FreeBSD
Our wasi target triple on "older" LLVM versions (<22) deviates from
the respective LLVM's defaults, so we need to align ports with that.
