[GMR] Fix a long-standing bug in GlobalsModRef where it failed to clear
out the per-function modref data structures when functions were deleted
or when globals were deleted.
I don't actually know how the global deletion side of this bug hasn't
been hit before, but for the other it just-so-happens that functions
aren't likely to be deleted in the particular part of the LTO pipeline
where we currently enable GMR, so we got lucky.
With this patch, I can self-host with GMR enabled in the normal pass
pipeline!
I was a bit concerned about the compile-time impact of this chang, which
is part of what motivated my prior string of patches to make the
per-function datastructure very dense and fast to walk. With those
changes in place, I can't measure a significant compile time difference
(the difference is around 0.1% which is *way* below the noise) before
and after this patch when building a linked bitcode for all of Clang.

Cleanup C++03 __invoke for Bullets 3 and 4.
The key changes in this patch are:
1. Remove the zero-argument overload in mem_fn. A member function must always
be invoked with at least one argument, the class instance. The zero-argument
operator()() in mem_fn would cause mem_fn to fail to compile when because
the call to '__invoke(pm)' is not well formed.
2. Prevent evaluation of '__apply_cv<Tp, Ret>' when 'Ret' is a function type.
'Ret' is a function type whenever 'Ret Tp::*' is a pointer to member function.
Attempting to add cv and ref qualifiers to a function type can cause a hard
compile error.
3. Remove the dummy overload __invoke(Rp Tp::*). It was present to help work
around #1. It will be replaced with a different '__invoke' overload that

supports lvalues but it will be used when the compiler supports rvalue
references but not variadic templates. This change makes sure we don't

2. Call objects for bullet 5 are now passed by reference and not value. Copying
the functor is incorrect. It will fail to compile for non-copyable functors
and it will discard cv-qualifiers on the call object, possibly leading to the
wrong function being called. I suspect that the reason the call object

fix invalid load folding with SSE/AVX FP logical instructions (PR22371)

https://bugs.winehq.org/show_bug.cgi?id=38826

The quick fix is to simply remove the scalar FP logical instructions from the load folding table
in X86InstrInfo, but that causes us to miss load folds that should be possible when lowering fabs,
fneg, fcopysign. So the majority of this patch is altering those lowerings to use *vector* FP
logical instructions (because that's all x86 gives us anyway). That lets us do the load folding
legally.

[opaque pointer type] Avoid using pointee types to retrieve InlineAsm's function type
As a stop-gap, retrieving the InlineAsm's function type was done via the
pointee type of its (pointer) Value type.
Instead, pass down and store the FunctionType in the InlineAsm object.
The only wrinkle with this is the ConstantUniqueMap, which then needs to
ferry the FunctionType down through the InlineAsmKeyType. This could be
done a bit differently if the ConstantInfo trait were broadened a bit to
provide an extension point for access to the TypeClass object from the
ValType objects, so that the ConstantUniqueMap<InlineAsm> would then be
keyed on FunctionTypes instead of PointerTypes that point to
FunctionTypes.
This drops the number of IR tests that don't roundtrip through bitcode*
without calling PointerType::getElementType from 416 to 8 (out of
10733). 3 of those crash when roundtripping at ToT anyway.
* modulo various unavoidable uses of pointer types when validating IR
(for now) and in the way globals are parsed, unfortunately. These
cases will either go away (because such validation will no longer be
necessary or possible when pointee types are opaque), or have to be
made simultaneously with the removal of pointee types.

This transformation produces:
```
for (int i = M; i < N; i++)
if (M < 0) break;
a[i] = 0;
}
```
Which can be unswitched into:
```
if (!(M < 0))
for (int i = M; i < N; i++)
a[i] = 0;
}
```
I went back and forth on whether the top level logic should live in
`SimplifyIndvar::eliminateIVComparison` or be put into its own
routine. Right now I've put it under `eliminateIVComparison` because
even though the `icmp` is not *eliminated*, it no longer is an IV
comparison. I'm open to putting it in its own helper routine if you
think that is better.

Use CGLoopInfo to emit metadata for loop hint pragmas.
When ‘#pragma clang loop vectorize(assume_safety)’ was specified on a loop other loop hints were lost. The problem is that CGLoopInfo attaches metadata differently than EmitCondBrHints in CGStmt. For do-loops CGLoopInfo attaches metadata to the br in the body block and for while and for loops, the inc block. EmitCondBrHints on the other hand always attaches data to the br in the cond block. When specifying assume_safety CGLoopInfo emits an empty llvm.loop metadata shadowing the metadata in the cond block. Loop transformations like rotate and unswitch would then eliminate the cond block and its non-empty metadata.
This patch unifies both approaches for adding metadata and modifies the existing safety tests to include non-assume_safety loop hints.

I'm basing this off AMD documentation - the intel docs on the support for PREFETCHW isn't clear whether Silvermont/Broadwell properly support PREFETCH but given that the intrinsic implementation is a default __builtin_prefetch call, it is safe whatever.

Fix `llvm-config` to emit the linker flag for the combined shared object built by autoconfig/make instead of the individual components.
Summary:
When LLVM is configured to build shared libraries, CMake builds each component as it's own shared object, while autoconfig/make builds them statically and then links them all together to create a single shared object. This change adds compile time config flags to `llvm-config` so it can know whether LLVM's components are separated or not and act accordingly.
This fixes `llvm-config` instead of fixing the makefiles to behave like CMake because, AIUI, LLVM's autoconfig/make build system is on the way out anyway.
This change only affects `llvm-config` from builds that use autoconfig/make.
