[x86] machine combiner reassociation: mark EFLAGS operand as 'dead'
In the commentary for D11660, I wasn't sure if it was alright to create new

From what I can see, the implicit operand is always created by the MachineInstrBuilder

reviewing the debug output, I noticed that the operand was not marked as 'dead'.
The machine combiner should do that to preserve future optimization opportunities

Linker: Fix references to uniqued nodes after r243883
r243883 started moving 'distinct' nodes instead of duplicated them in
lib/Linker. This had the side-effect of sometimes not cloning uniqued
nodes that reference them. I missed a corner case:
!named = !{!0}
!0 = !{!1}
!1 = distinct !{!0}
!0 is the entry point for "remapping", and a temporary clone (say,
!0-temp) is created and mapped in case we need to model a uniquing
cycle.
Recursive descent into !1. !1 is distinct, so we leave it alone,
but update its operand to !0-temp.
Pop back out to !0. Its only operand, !1, hasn't changed, so we don't
need to use !0-temp. !0-temp goes out of scope, and we're finished
remapping, but we're left with:
!named = !{!0}
!0 = !{!1}
!1 = distinct !{null} ; uh oh...
Previously, if !0 and !0-temp ended up with identical operands, then
!0-temp couldn't have been referenced at all. Now that distinct nodes
don't get duplicated, that assumption is invalid. We need to
!0-temp->replaceAllUsesWith(!0) before freeing !0-temp.

there was no case of this in the open source bootstrap I'd done before

[UB] Fix a nasty place where we would pass null pointers to memcpy.
This happens to work, but is not guaranteed to work. Indeed, most memcpy
interfaces in Linux-land annotate these arguments as nonnull, and GCC
and LLVM both can and do optimized based upon that. When they do so,
they might legitimately have miscompiled code calling this routine with
two valid iterators, 'nullptr' and 'nullptr'. There was even code doing
precisely this because StringRef().begin() and StringRef().end() both
produce null pointers.
This was found by UBSan.

[AArch64] Vector FCOPYSIGN supports Custom-lowering: mark it as such.
There's a bunch of code in LowerFCOPYSIGN that does smart lowering, and
is actually already vector-aware; let's use it instead of scalarizing!
The only interesting change is that for v2f32, we previously always used
use v4i32 as the integer vector type.
Use v2i32 instead, and mark FCOPYSIGN as Custom.

[CodeGen] Fix FCOPYSIGN legalization to account for mismatched types.
We used to legalize it like it's any other binary operations. It's not,
because it accepts mismatched operand types. Because of that, we used
to hit various asserts and miscompiles.
Specialize vector legalizations to, in the worst case, unroll, or, when
possible, to just legalize the operand that needs legalization.
Scalarization isn't covered, because I can't think of a target where
some but not all of the 1-element vector types are to be scalarized.

-Wdeprecated-clean: Fix cases of violating the rule of 5 in ways that are deprecated in C++11
Various value handles needed to be copy constructible and copy
assignable (mostly for their use in DenseMap). But to avoid an API that
might allow accidental slicing, make these members protected in the base
class and make derived classes final (the special members become
implicitly public there - but disallowing further derived classes that
might be sliced to the intermediate type).
Might be worth having a warning a bit like -Wnon-virtual-dtor that
catches public move/copy assign/ctors in classes with virtual functions.
(suppressable in the same way - by making them protected in the base,
and making the derived classes final) Could be fancier and only diagnose
them when they're actually called, potentially.
Also allow a few default implementations where custom implementations
(especially with non-standard return types) were implemented.
