[CIR] Allow _setjmp and _setjmpex to fall through to library calls (#193021)
This change allows calls to _setjmp and _setjmpex to fall through the
builtin handling and be emitted as library calls when we are not
targeting OSMSVCRT. It also adds the code to set "returns_twice" on
functions matching an explicit list, as they are in classic codegen.
[dsymutil] Add --embed-resource to copy files into dSYM bundles. (#190663)
Add a new --embed-resource flag that copies files or directories into
the dSYM bundle's Contents/Resources/ directory during generation.
Projects often need to embed files such as LLDB Python scripts into dSYM
bundles, and this is usually done with a post dsym generation script,
which may race stripping and code signing steps.

[llvm-nm] Drop STT_FILE/STT_SECTION from --special-syms (#192129)
The filter for SF_FormatSpecific symbols exempted all such symbols
for architectures having mapping symbols. This caused STT_FILE and
STT_SECTION symbols to appear with --special-syms on these targets
but not on x86_64. Narrow the exemption to only STT_NOTYPE symbols,
which are the actual mapping symbols ($d, $x, etc.).
[HLSL] Add codegen for accessing resource members of a struct (#187127)
Any expression that accesses a resource or resource array member of a global struct instance must be during codegen replaced by an access of the corresponding implicit global resource variable.
When codegen encounters a `MemberExpr` of a resource type, it traverses the AST to locate the parent struct declaration, building the expected global resource variable name along the way. If the parent declaration
is a non-static global struct instance, codegen searches its `HLSLAssociatedResourceDeclAttr` attributes to locate the matching global resource variable and then generates IR code to access the resource global in place of the member access.

dmu_direct: avoid UAF in dmu_write_direct_done()
dmu_write_direct_done() passes dmu_sync_arg_t to
dmu_sync_done(), which updates the override state and
frees the completion context. The Direct I/O error path
then still dereferences dsa->dsa_tx while rolling the
dirty record back with dbuf_undirty(), resulting in a
use-after-free.
Save dsa->dsa_tx in a local variable before calling
dmu_sync_done() and use that saved tx for the error
rollback. This preserves the existing ownership model
for dsa and does not change the Direct I/O write
semantics.

[mlir][MemRef][GPU] Migrate GPU dialect ops to IndexedAccessOpInterface (#190380)
This commit migrates the handling of GPU dialect ops in
fold-memref-alias-ops from hard-coded support to the new
IndexedAccessOphinterface, which also adds expand_shape folding support
for those ops.
Once other memref-dialect passes are migrated to use this interface,
this will allow us to break the dependency between the memref and gpu
dialects.

[flang][cuda] Only apply the implicit data attribute on the component for use_device (#192146)
For interoperability between CUDA Fortran and OpenACC, the OpenACC
host_data use_device clause needs implicitly add the DEVICE attribute to
the object symbol for the duration of the region. When the object was a
component, we were adding the symbol to the base which is not what we
want.
Update the handling to copy the base symbol with a new DerivedTypeScope
and set the attribute on the component. New test is added to test the
behavior is indeed on the component.
Option to control signaling NaN support
This change implements the Clang command-line option `-fsignaling-nans`,
which is a counterpart of the GCC option with the same name. It allows a
user to control support for signaling NaNs. This option instructs the
compiler that signaling NaNs are to be treated according to IEEE 754:
they are quieted in arithmetic operations and raise `Invalid`
floating-point exception. The opposite option, `-fno-signaling-nans`,
does the reverse, - it indicates that signaling NaNs are handled
identically to quiet NaNs. If neither of these options is specified, no
signaling NaNs support is assumed, except for functions that have
`strictfp` attribute.
At the IR level, signaling NaN support is represented by the function
attribute "signaling-nans". It is set by Clang when it generates code in
cases when signaling NaNs are supported. If the target architecture does
not support signaling NaNs, Clang does not set this attribute.
The primary motivation for this change is the optimization of strictfp

zpool-labelclear.8: Warn that it's destructive
If I could go back in time, I would beg Sun engineers to pick a
different name. For those of us who have not read the ZFS On-Disk
Specification pdf, it is not at all obvious that clearing a "label" is
such a bad thing.
But changing the name would be a breaking change, so at least for now
we can update the documentation.
