[CMake] Don't LTO optimize targets on Darwin either

This is a follow up to D102732 which also expands the logic to Darwin.

[TargetLowering][ARM] Don't alter opaque constants in TargetLowering::ShrinkDemandedConstant.

We don't constant fold based on demanded bits elsewhere in
SimplifyDemandedBits, so I don't think we should shrink them either.

The affected ARM test changes because a constant become non-opaque
and eventually enabled some constant folding. This no longer happens.
I checked and InstCombine is able to simplify this test. I'm not sure exactly
what it was trying to test.

[InstSimplify] move extract with undef index fold; NFC

This puts it closer to the other undef query check and
will avoid a potential ordering problem if we allow
folding non-constant-int indexes.

[AArch64][v8.3A] Avoid inserting implicit landing pads (PACI*SP)

PACI*SP have the advantage that they are in HINT space, meaning
they can be run successfully in hardware without PAuth support -
they will just behave as a NOP. However, PACI*SP are also implicit
landing pads (think of an extra BTI jc). Therefore, they allow
indirect jumps of all kinds into them, potentially inserting new
gadgets. This patch replaces PACI*SP by PACI* LR, SP when
compiling explicitly for hardware with full PAuth support. PACI*
is not in the HINT space, therefore it will fault when run in
hardware without PAuth support, but it is also not a landing pad,
making programs safer in newer HW.
