[libc] Add --json mode for hdrgen (#127847)
This adds a feature to hdrgen to emit JSON summaries of header
files for build system integration. For now the summaries have
only the basic information about each header that is relevant for
build and testing purposes: the standards and includes lists.
nfscl: Return appropriate reply status for NFSv4.1 callbacks
Certain NFSv4.1 callbacks are not currently supported/used
by the FreeBSD client. Without this patch, NFS4ERR_NOTSUPP
is replied for the callbacks. Since NFSv4.1 does not specify
all of these callbacks as optional, I think it is preferable
to reply NFS_OK or NFS4ERR_REJECT_DELEG instead of NFS4ERR_NOTSUPP.
This patch changes the reply status for these unsupported
callbacks, which the client has no use for.
I am not aware of any NFSv4.1 servers that will perform
any of these callbacks against the FreeBSD client at this time.

[lldb] Store the return SBValueList in the CommandReturnObject (#127566)
There are a lot of lldb commands whose result is really one or more
ValueObjects that we then print with the ValueObjectPrinter. Now that we
have the ability to access the SBCommandReturnObject through a callback
(#125006), we can store the resultant ValueObjects in the return object,
allowing an IDE to access the SBValues and do its own rich formatting.

Add back deleted test for llvm-dwarfdump JSON output (#127685)
Looks like https://github.com/llvm/llvm-project/pull/124936 was reverted
(for modifying JSON output), but the test for JSON output with errors
was deleted in https://github.com/llvm/llvm-project/pull/126587 (to
attempt to fix failing build)
This will add back a test and a new one for llvm-dwarfdump to validate
the JSON for errors. One case where the sub-categories will eventually
appear and another where not.
test plan:
ninja check-llvm-tools-llvm-dwarfdump
[Clang] Fix cross-lane scan when given divergent lanes (#127703)
Summary:
The scan operation implemented here only works if there are contiguous
ones in the executation mask that can be used to propagate the result.
There are two solutions to this, one is to enter 'whole-wave-mode' and
forcibly turn them back on, or to do this serially. This implementation
does the latter because it's more portable, but checks to see if the
parallel fast-path is applicable.
Needs to be backported for correct behavior and because it fixes a
failing libc test.
[CUDA] Add support for sm101 and sm120 target architectures (#127187)
