[flang][optimize] Use ArraySectionAnalyzer to better handle aliasing sections (#180595)
When alias analysis reports potential aliasing between LHS and RHS when
inlining `hlfir.assign`, use `ArraySectionAnalyzer` to determine if the
sections are disjoint or identical, which is safe for element-wise
assignment.

[mlir][IR] `DenseElementsAttr`: Remove `i1` dense packing special case (#180397)
`DenseElementsAttr` stores elements in a `ArrayRef<char>` buffer, where
each element is padded to a full byte. Before this commit, there used to
be a special storage format for `i1` elements: they used to be densely
packed, i.e., 1 bit per element. This commit removes the dense packing
special case for `i1`.
This commit removes complexity from `DenseElementsAttr`. If dense
packing is needed in the future it could be implemented in a general way
that works for all element types (based on #179122).

[Clang] [Sema] Fix FixIt for implicit-int diagnostics. (#179356)
When encountering a declaration without a type specifier, in contexts
where they could reasonably be assumed to default to int, clang emits a
diagnostic with FixIt. This FixIt does not produce working code.
This patch updates `SemaType` to correctly insert a single int type
specifier per group of declarations, and adds coverage in the FixIt lit test suite.
Fixes #179354
freebsd-update: Error for -b basedir without UNAME_r set
freebsd-update sets the currently running release from UNAME -r, which
can be overridden via the --currently-running commandline option (or by
setting UNAME_r in the environment). This may be invalid if -b is used
to specify a basedir other than /, so error out if -b is specified
without setting the currently running version.

[lldb] Move parts of OutputFormattedUsageText into utility function (#180947)
As seen in #177570, this code has a bunch of corner cases, does not
handle ANSI codes properly and does not handle unicode at all. That's
enough to fix that we need some tests to make it clear where we're
starting from.
The body of OutputFormattedUsageText is moved into a utility in the
AnsiTerminal.h header and tests added to the existing
AnsiTerminalTest.cpp.
Some results are known to be wrong. Some that cause crashes are
commented out, to be enabled once fixed.
[Matrix] Use tiled loops automatically for large kernels. (#179325)
Update LowerMatrixIntrinsics to use tiled loops automatically in for
larger matrixes. The fully unrolled codegen creates a huge amount of
code, which performs noticably worse then the tiled loop nest variant.
We new try to estimate the number of instructions needed for the
multiply, and if it is too large, tiled loops are used. The current
threshold is anything roughly larger than 6x6x6 double multiply.
Eventually I think we want to only generate tiled loops. This patch is a
first step, trying to opt in for cases where we know it is beneficial.
Checked on AArch64, but should help on other architectures similarly,
and also drastically reduce binary size + compile time.

[mlir][shard, mpi] Allow more than one last axis to be "unsplit" (#180754)
A resharding pattern allowed only a single trailing axis to be
"unsplit".
This PR allows multiple trailing axes to be "unsplit".
wip/srecord -- update package to v1.65
Upstream switched to cmake
Since there are no knobs to make the extensive html and pdf
documentation optional, we just slash and burn. If desired, there
could be a separate doc package.
