[SpecialCaseList] Add backward compatible dot-slash handling
This PR is preparation for:
* https://github.com/llvm/llvm-project/pull/167283
The new behavior is controlled by the `Version` field in the special
case list file.
- Version 1 and 2: Path is matched as-is, regardless of presence of "./".
- Version 3, 5 and higher: Paths with leading dot-slash are canonicalized
to paths without dot-slash before matching. This means that a rule
like `src=./foo` will never match, and `src=foo` will match both
`foo` and `./foo`. (Version 3 never became default but has this behavior).
- Version 4: Transitionary version. Paths are matched both ways
(canonicalized and non-canonicalized) to maintain backward compatibility.
If a match only works with the old behavior (non-canonicalized), a warning
is emitted.
This change allows for a gradual transition to the new behavior, while

net/cloudflared: make only header static
Feature will be new in 26.1.10, apparently an omission from
an earlier extension pertaining to dialogs but not forms.
Revert "improve renice user error messages"
This reverts commit 925f53682469ea12c017b48114b16e8f1627fb0b. The tests are wrong,
so I'm reverting and reopening the pull request.
[X86][APX] Enable PP2/PPX generation on Windows (#202984)
Revert restrictions from
https://github.com/llvm/llvm-project/pull/178122 which disabled
PUSH2/POP2/PPX on Windows due to missing unwinder opcodes. Now that
unwinder support has landed, this is no longer needed.
The parent process for a CGI request exits after all input
data to the CGI is received and leaves the CGI reparented
to init. This prevents controlling concurrency when httpd
is run by e.g. inetd.
Exchange input and output processes for a CGI request so that
output processing is done by the parent httpd so that the parent
stays until the CGI is done.
[Clang][AMDGPU] Add ``amdgcn_av("none")`` attribute for atomic expressions
Add a statement attribute that suppresses MakeAvailable/MakeVisible
cache operations on AMDGPU atomic instructions while preserving memory
ordering (waits).
The attribute takes a string argument specifying the mode. Currently
"none" is the only supported mode. The resulting atomic or fence
instruction carries !mmra !{!"amdgcn-av", !"none"} metadata.
