[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
Fixes #190388
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
GPIO using pin control
New drivers:
- GPIO-by-pin control driver (also appearing in the GPIO pull
request) fulfilling a promise on a comment from Grant Likely many
years ago: "can't GPIO just be a front-end for pin control?" it

Stop cleaning gem artifacts
Bulk builds have seen occasional failures building
textproc/ruby-commonmarker, which is the only reverse dependency. I'm
not positive the cleaning of gem artifacts is the cause of the failure,
though I suspect it is.

[SLP][NFC] Simplify range/type accessors
Use the range-friendly llvm::accumulate() overload instead of the
two-iterator std::accumulate() form, drop redundant cast<>/dyn_cast<>
calls where the source already provides a typed accessor.
