Pull misc x86 updates from Dave Hansen:
"The usual smattering of x86/misc changes.
The IPv6 patch in here surprised me in a couple of ways. First, the
function it inlines is able to eat a lot more CPU time than I would
have expected. Second, the inlining does not seem to bloat the kernel,
at least in the configs folks have tested.
- Inline x86-specific IPv6 checksum helper
- Update IOMMU docs to use stable identifiers
- Print unhashed pointers on fatal stack overflows"

[IROutliner] Add TTI Hook for Propagating Attributes (#153985)
On RISC-V, the interrupt attribute relates only to the prolog and epilog
of the attributed function (and has specific restrictions on the
function's signature). It does not change how that function calls other
functions, and when outlining, the outlined function must not have this
attribute.
This adds a target-independent hook to TTI so targets can choose which
attributes to propagate (by default all are propagated).
Fixes #149969

[llubi] Add UTC helper (#180603)
This patch adds a UTC helper `llvm/utils/update_llubi_test_checks.py` to
generate check lines for the trace. Generalizer and multiple prefixes
are not supported since they are meaningless for traces. I know it is a
bit weird, but I don't have a better idea :(
I found that `llvm/utils/update_test_body.py` also works. But it is
annoying to duplicate the command twice.
