[llvm-ar] Enable failed testacase on FreeBSD (#192612)
FreeBSD used to allow the read system call on directory file descriptors
(dirfd). In those cases, it returned the internal file data structure
instead of failing. This caused the llvm-ar test— which expects a
failure when attempting to read a directory— to pass incorrectly.
This behavior existed for compatibility with older Unix implementations,
but it was removed in commit dcef4f65ae3978c50eab745f67364db4660a9f43.
The change applies to FreeBSD 13 and later. Since FreeBSD 12 has also
reached end-of-life, the outdated behavior is no longer relevant.
As a result, the test now behaves as intended and can be safely
re-enabled.
auth2-chall.c: fix merging botch that broke basic functionality
Addresses PR bin/60196 "OpenSSH keyboard-interactive/pam authentication
fails to work after the update to 10.3".
This issue would also have affected S/Key functionality from what I
see, though I have no means of testing this. Also "BSD auth", but
that's not enabled by us.

[clang] implement CWG2064: ignore value dependence for decltype
The 'decltype' for a value-dependent (but non-type-dependent) should be known,
so this patch makes them non-opaque instead.
This patch also implements what's neceessary to allow overloading
on pure differences in instantiation dependence, making `std::void_t`
usable for SFINAE purposes.
This also readds a few test cases from da98651, which was a previous attempt
at resolving CWG2064.
Fixes #8740
Fixes #61818

floating point state leakage can be observed on AMD Zen/Zen+ (Zen 1)
This was discovered by the Rootsec research group at the CISPA Helmholtz
Center for Information Security. Rootsec named the problem
Floating Point Divider State Sampling (FP-DSS).
Do AMD's suggested mitigation, setting a chicken bit in an MSR.

Pull pin control updates from Linus Walleij:
"Core changes:
- Perform basic checks on pin config properties so as not to allow
directly contradictory settings such as setting a pin to more than
one bias or drive mode
- Handle input-threshold-voltage-microvolt property
- Introduce pinctrl_gpio_get_config() handling in the core for SCMI
