ZTS: add targeted redundancy_draid_spare exception

When sequentially resilvering a dRAID pool it's possible that a few
correctable checksum errors will be reported.  This is a known issue
which is occasionally observed in the CI.  Until it's resolved we
want the test case to tolerate a few checksum errors in this scenario
to prevent false positives in the CI.

This change also has the additional side effect of standardizing in
one location how the dRAID pool integrity is verified.

[Clang] Fix sret AS for non-trivial-copy returns. (#186275)

classifyReturnType used getAllocaAddrSpace() for sret, which is wrong
on targets like AMDGPU where alloca lives in addrspace(5). For types
with deleted copy/move constructors, there is no way to construct into
a temp and copy out — the sret pointer must point directly to the caller's 
destination in the default address space.

Add a target hook getSRetAddrSpace() so AMDGPU can return LangAS::Default
for non-register-passable types.

Fixes issue #185744

geom manuals: Clarify units

The gpart manual says that sizes are specified in blocks, unless an SI
unit suffix is provided. This confuses new operators because GEOM uses
binary bytes, a large difference at modern storage pool sizes. Rewrite
suffixes in all GEOM manuals to consistently clarify this, matching what
we and the rest of the industry have been doing in other documentation.
While here, use non-breaking spaces between numbers and units, unless
they are already written with a hyphen.

Fix memory corruption bugs in BSM record parsing

fetch_newgroups_tok(3): clamp group count to AUDIT_MAX_GROUPS before the
loop to prevent a stack buffer overflow when a crafted record specifies
more than 16 groups.

fetch_execarg_tok(3), fetch_execenv_tok(3): add a bounds check at the
top of the string-walking loop to prevent an out-of-bounds read when the
previous string's nul byte is the last byte of the record buffer.

fetch_sock_unix_tok(3): clamp the memchr search length to the number of
bytes remaining in the buffer to prevent an out-of-bounds read on short
tokens. Also clamp slen to sizeof(path) to prevent a one-byte overflow
when no nul byte is found within the path data.

fetch_socket_tok: fix copy-paste error where the remote address was
written into l_addr instead of r_addr.

[flang] Add parser support for Fortran 2023 conditional arguments (F2023 R1526-R1528) (#191303)

Implement parsing, unparsing, and parse tree nodes for the Fortran 2023
conditional argument syntax (F2023 R1526-R1528). This enables calls of
the form:

  call sub((flag ? a : b))
  call sub((x > 10 ? a : x > 5 ? b : c))
  call sub((flag ? a : .NIL.))

- Add ConditionalArg and ConditionalArgTail parse tree nodes
- Add Nil empty class for .NIL. representation
- Add ConditionalArg as a new alternative in ActualArg
- Add parser rules for conditional-arg, consequent, and chained branches
- Add unparse support for round-trip printing
- Add dump-parse-tree and FeatureList support
- Add parser tests covering simple, multi-branch, .NIL., BOZ, NULL(),
keyword arguments, and module procedure cases

[mlir][canonicalize] Add filter-dialects option (#193041)

Add a new `filter-dialects` list option to the canonicalize pass. When
provided, only canonicalization patterns from the listed dialects are
collected, and the named dialects are force-loaded via
getDependentDialects.

Loading flow: the Canonicalizer's getDependentDialects override calls
`registry.addDialectToPreload(name)` for each filter-dialect name, which
records the name in a new `dialectsToPreload` list on DialectRegistry.
The PassManager's pipeline-init then calls
`dependentDialects.preloadSelectDialects(ctx, emitError)`, which loads
each preload entry via `context->getOrLoadDialect(name)` — the real
allocator is resolved from the context's own registry (registered by
the tool) and the dialect is loaded before multi-threaded execution
begins. If a requested dialect has no registration in the context, a
diagnostic `"can't load dialect '<name>': missing registration?"` is
emitted.

[PreISelIntrinsicLowering] Use index type for index in intrinsic expansion (#193807)

We'd chosen intptr type for the binary in review, but on reflection the
index type is probably a conceptually better fit. On riscv, these are
going to be the same, so it's purely a conceptual issue.

For the unary case, this is an actual change since we were using i64
unconditionally. This improves codegen for RV32 by avoiding the need for expensive legalization of i64 expressions for the IV.

   lint, make: only enable strict bool mode when using GCC

   The GCC precompiler marks each token whether it comes from a system
   header. Lint uses this information to allow some expressions that aren't
   strictly bool, such as in __predict_true and __predict_false. The Clang
   preprocessor treats all tokens as not coming from system headers, thus
   being too strict.
