[orc-rt] Remove doxygen comments from logging implemenetation APIs (#209086)
These APIs are intended for internal consumption by the ORC runtime's
logging system: plain comments are more appropriate here than doxygen
comments.
[llvm-profgen][test] Split tests by target architecture (#207724)
The top-level llvm-profgen lit configuration previously disabled the
entire test directory unless the X86 target was registered. As a result,
target-independent tests and tests for ARM and AArch64 also implicitly
depended on X86.
Split target-specific tests and inputs into X86, ARM, and AArch64
directories with per-directory lit.local.cfg files. Leave help.test at
the top level because it is target-independent. Existing X86 tests
remain guarded by X86 and run as before, while ARM and AArch64 tests no
longer require the X86 target. The X86 non-ARM ETM rejection case also
no longer requires the ARM target; it only requires X86 and OpenCSD.
Split the former etm-arch.test into ARM/etm-arch.test, containing the
two ARM-specific checks, and X86/etm-non-arm.test, containing the
existing X86 rejection check. The tested inputs and expected diagnostics
are preserved.

[IR] Handle vector tys in ConstantExpr::getIntrinsicIdentity for smin/max. (#208367)
The code was using getIntegerBitWidth() when it should have been using
getScalarSizeInBits(). This resulted in an assert in debug builds, and
who-knows-what in opt builds.
Reproducer:
```
define <4 x i32> @f(<4 x i32> %a, i32 %b) {
%c = call <4 x i32> @f(<4 x i32> %a, i32 %b)
%m = call <4 x i32> @llvm.smax.v4i32(<4 x i32> %c, <4 x i32> %a)
ret <4 x i32> %m
}
$ opt -passes=tailcallelim repro.ll
Casting.h:572: Assertion `isa<To>(Val) && "cast<Ty>() argument of
incompatible type!"' failed.

[libc] Make cpp::expected::operator bool explicit (#208681)
Without explicit, expected<T, E> implicitly converts to bool in all
sorts of unexpected contexts (e.g. `EXPECT_EQ(ErrorOr<int>(47), 1)`),
and also deviates from std::expected in C++23.
While in there, add basic unit tests for expected and unexpected (we
didn't have any tests for this utility yet), and update the file header.

[RISCV][P-ext] Replace RISCVISD::PPAIRE_DB with RISCVISD::PPAIRE. NFC (#208980)
This replaces RISCVISD::PPAIRE_DB with the RISCVISD::PPAIRE added by
#208763.
This adds two CONCAT_VECTORS and two EXTRACT_SUBVECTORs during lowering
instead of waiting until isel to form the GPR pairs.
[ADT] Introduce EytzingerTableSpan (#208885)
This patch introduces EytzingerTableSpan, a non-owning view of a buffer

order.

Use requests.Session for ET-Telemetry requests (#5553)
The current code loops through every telemetry event to submit and makes a standalone POST request, resulting in a DNS lookup for each item. This results in a ton of DNS requests for the same domain every time this script runs, which is every minute due to the cron job that executes it. This patch changes the behavior by establishing a requests Session object and then making the POST requests from that, resulting in a single DNS lookup, and as an added benefit, the script completes much faster.
[orc-rt] Add os_log logging backend (Darwin only) (#209081)
Implement the os_log backend, selected with ORC_RT_LOG_BACKEND=os_log.
With this backend selected, the ORC_RT_LOG macros expand at the call
site to os_log_with_type. Each ORC runtime log level maps to an
os_log_type_t (error -> ERROR, warning -> DEFAULT, info -> INFO, debug
-> DEBUG). The compile-time ORC_RT_LOG_LEVEL floor still applies, but
runtime filtering is left to the system (e.g. `log config`), so the
printf backend's ORC_RT_LOG and ORC_RT_LOG_OUTPUT have no effect.
Records go to the "org.llvm.orc-rt" subsystem with the category as the
os_log category. (Per-category handles are created on first use and
cached).
Add regression tests under test/regression/logging/os_log:
no-printf-output.test checks that the backend produces no console
output, and an opt-in delivery test (llvm-lit --param
run-os-log-tests=1) scrapes `log show` to confirm records reach the
expected subsystem and category.
[Flang] Fix for the spurious error for VOLATILE actual argument in implicit interface CALL (#192605)
Fixes #191343
Replaced the error with warning. Now it permits calling an external
procedure with implicit interface and passing a volatile argument. There
will be a warning that the procedure should have an explicit interface.
In addition to fixing the VOLATILE error, I updated the semantic check
for the ASYNCHRONOUS attribute. Both attributes were incorrectly
throwing a hard error when used as actual arguments in an implicit
interface call. According to the Fortran 2018 standard, an explicit
interface is only mandatory when the dummy argument has the VOLATILE or
ASYNCHRONOUS attribute. Since the standard doesn't restrict actual
arguments in this scenario, I downgraded both to emit a
-Wimplicit-interface-actual warning instead.
