[LV] Add test for cost of widened pointer induction (NFC). (#223153)
Add a cost test where the pointer induction is used as a value and
remains a VPWidenPointerInductionRecipe.

[SCEV] Directly form add recurrences for simple pointer IVs. (#222915)
Add support for PN = PHI(Start, gep Self, LoopInvariant) to
createSimpleAffineAddRec.
This allows to handle simple pointer IVs without going through the more
expensive createAddRecFromPHI machinery in many cases.
This is not completely NFC: previously we created SCEVUnknown for a
trivial AddRec with step 0, now we return the start value.
This gives a modest geomean compile-time decrease

LICM: Drop -licm-force-thread-model-single in favor of the module flag
Now that the threading model is carried by the "thread-model" IR module flag,
the hidden -licm-force-thread-model-single override is redundant: a test can
select the single-threaded model by setting the module flag directly.
isThreadLocalObject reads only Module::getThreadModel.

CodeGen: Replace TargetOptions::ThreadModel with module flag
Migrate the threading-model consumers off TargetOptions::ThreadModel and onto
the "thread-model" module flag. The main user was ARM's pass config, which is
moved into AtomicExpand, which now performs the single-thread expansion
directly.
Few tests use the -thread-model flag, so delete it and migrate those cases
to use the module flag.

[libc++][docs] Use Furo theme
Adopt the shared LLVM Furo configuration and wyvern logo, widen the content area on desktop viewports, and remove page-local contents directives that duplicate Furo's navigation.
[libc] Enable Float80-type for x86_32 (#221408)
Enables for x86_32 by using Uint<96>
```CPP
struct Float80 {
#if __SIZEOF_LONG_DOUBLE__ == 12
UInt<96> bits;
#else
UInt128 bits;
#endif
```
for testing it on x86_32
it needs -m32 and --msse2 extra flags other than your usual cmake for x86_32

powerpc/pmap: Add a minimum TID width
QEMU doesn't appear to emulate the MMUCFG register for Book-E CPUs, so
give a sane small default of 7, for an 8 bit PID register.
website/contact: Remove GitHub advice
The doc project has demonstrated a consistent and united consensus that
we do not want to receive patches on GitHub. Remove the suggestion to
send patches on the GitHub silo that only carlavilla and I will see.
