[GlobalISel] add G_ROTL, G_ROTR to computeKnownBits (#166365)
Adresses one of the subtasks of #150515.
The code is ported from `SelectionDAG::computeKnownBits` and tests are
loosely based on `AArch64/GlobalISel/knownbits-shl.mir`.
daemon: Add option for output file mode
The daemon utility has always created its output file with a fixed mode
of 0600. This causes issues for log collection setups where the collector
does not run as root but instead relies on group access to the watched
daemon’s log file.
Introduce a new option that allows specifying the output file mode using
install(1)-style semantics. This enables non-root log collectors to access
the file as intended and improves compatibility with log rotation tools.

From des at FreeBSD dot org:
* Use fork(2) instead of vfork(2), preventing a race between the parent
updating pidlist and the child iterating over it.
* Move fdopen(3) calls form pdes_parent() to pdes_get() so we can fail
if fdopen(3) fails, e.g. if the file descriptors are too big.
libfetch: Check for failure to create SSL context
* Drop the ssl_meth member, there is no reason to hang on to it.
* Replace deprecated SSLv23_client_method() with TLS_client_method().
* Check the return value from SSL_CTX_new().

[LSR] Support SCEVPtrToAddr in SCEVDbgValueBuilder.
Allow SCEVPtrToAddr as cast in assertion in SCEVDbgValueBuilder.
SCEVPtrToAddr is handled similarly to SCEVPtrToInt.
Fixes a crash with debug info after bd40d1de9c9ee, which started to
generate ptrtoaddr instead of ptrtoint expressions.
[mlir][Interfaces] Add `ExecutionProgressOpInterface` + folding pattern (#179039)
Add the `ExecutionProgressOpInterface` with an interface method to check
if an operation "must progress". Add `mustProgress` attributes to
`scf.for` and `scf.while` (default value is "true").
`mustProgress` corresponds to the [`llvm.loop.mustprogress`
metadata](https://llvm.org/docs/LangRef.html#langref-llvm-loop-mustprogress).
Also add a canonicalization pattern to erase `RegionBranchOpInterface`
ops that must progress but loop infinitely (and are non-side-effecting).
This canonicalization pattern is enabled for `scf.for` and `scf.while`.

Fix build after #179039.
[ValueTracking] Propagate sign information out of loop (#175590)
LLVM converts sqrt libcall to intrinsic call if the argument is within
the range(greater than or equal to 0.0). In this case the compiler is
not able to deduce the non-negativity on its own. Extended ValueTracking
to understand such loops.
Fixes llvm/llvm-project#174813
