Currently, TargetLibraryInfoWrapperPass is inserted by PMBuilder.
However, some passes are inserted manually before the PMBuilder
ones - if any of them happens to use TargetLibraryInfoWrapperPass,
it'll get a default-constructed one, with an unknown target triple.
This happens to InstrProfiling in D21736, breaking it.

https://reviews.llvm.org/D25932 made it so that clang always checks if
libLTO.dylib is present on disk, even if -flto is not being used. The
motivation for that change was that if a dependency happens to contain bitcode,
ld64 will try to load libLTO without -flto explicitly being enabled. However,
the change had the undesirable side effect of warning if libLTO.dylib doesn't
exist even if it isn't needed.
Change things so that -lto_library is always passes, independent of if it
exists or not. ld64 only looks at this flag if it uses LTO. If the dylib
exists, all is well. If it doesn't, and LTO is not being used, all is well too.
If ld64 does end up using LTO and the dylib does not exist, ld64 will print
something like
ld: could not process llvm bitcode object file, because foo/libLTO.dylib could not be loaded file 'test.o' for architecture x86_64

Summary:
The new error information contains the type of error (e.g. overlap or bad file path)
and the replacement(s) that is causing the error. This enables us to resolve some errors.
For example, for insertion at the same location conflict, we need to know the
existing replacement which conflicts with the new replacement in order to calculate
the new position to be insert before/after the existing replacement (for merging).

This is needed because whether the constructor is deleted can control whether
we pass structs by value directly.
To fix this properly we probably want a more direct way for CodeGen to ask
whether the constructor was deleted.

of a method that was declared in an invalid interface
This commit fixes an infinite loop that occurs when clang tries to iterate over
redeclaration of a method that was declared in an invalid @interface. The
existing validity checks don't catch this as that @interface is a duplicate of
a previously declared valid @interface declaration, so we have to verify that
the found redeclaration is in a valid declaration context.

This commit adds a new predefined macro named __OBJC_BOOL_IS_BOOL that describes
the Objective-C boolean type: its value is zero if the Objective-C boolean uses
the signed character type, otherwise its value is one as the Objective-C boolean
uses the builtin boolean type.

with __unknown_anytype return type.
When the following code is compiled, Sema infers that the type of
__unknown_anytype is double:
extern __unknown_anytype func();
double *d = (double*)&func();
This triggers an assert in CodeGenFunction::EmitCallExprLValue because
it doesn't expect to see a call to a function with a non-reference
scalar return type.
This commit prevents the assert by making VisitUnaryAddrOf error out if
the address-of operator is applied to a call to a function with
__unknown_anytype return type.

Summary:
This is a simple sema check patch for arguments of `__builtin_arm_rsr` and the related builtins, which currently do not allow special registers with indexes >7.
Some of the possible register name formats these builtins accept are:
```
{c}p<coprocessor>:<op1>:c<CRn>:c<CRm>:<op2>
```
```
o0:op1:CRn:CRm:op2
```
where `op1` / `op2` are integers in the range [0, 7] and `CRn` / `CRm` are integers in the range [0, 15].
The current sema check does not allow `CRn` > 7 and accepts `op2` up to 15.

StartFunction enters a release cleanup for ns_consumed arguments in
ARC, so we need to balance that somehow. We could teach StartFunction
that it's emitting a delegating function, so that the cleanup is
unnecessary, but that would be invasive and somewhat fraught. We could
balance the consumed argument with an extra retain, but clearing the
original variable should be easier to optimize and avoid some extra work
at -O0. And there shouldn't be any difference as long as nothing else
uses the argument, which should always be true for the places we emit
delegate arguments.
Fixes PR 27887.

Summary:
This used to work because system headers are found in a (somewhat)
predictable set of locations on Linux. But this is not the case on
MacOS; without this change, we don't look in the right places for our
headers when doing device-side compilation on Mac.

Summary:
Compiling CUDA device code requires us to know the host toolchain,
because CUDA device-side compiles pull in e.g. host headers.
When we only supported Linux compilation, this worked because
CudaToolChain, which is responsible for device-side CUDA compilation,
inherited from the Linux toolchain. But in order to support MacOS,
CudaToolChain needs to take a HostToolChain pointer.
Because a CUDA toolchain now requires a host TC, we no longer will
create a CUDA toolchain from Driver::getToolChain -- you have to go
through CreateOffloadingDeviceToolChains. I am *pretty* sure this is
correct, and that previously any attempt to create a CUDA toolchain
through getToolChain() would eventually have resulted in us throwing
"error: unsupported use of NVPTX for host compilation".
In any case hacking getToolChain to create a CUDA+host toolchain would
be wrong, because a Driver can be reused for multiple compilations,
potentially with different host TCs, and getToolChain will cache the
result, causing us to potentially use a stale host TC.
So that's the main change in this patch.
In addition, we have to pull CudaInstallationDetector out of Generic_GCC
and into a top-level class. It's now used by the Generic_GCC and MachO
toolchains.

I made several changes for consistency with the rest of x86 instrinsics header files. Some of these changes help to render doxygen comments better.
1. avxintrin.h – Moved the opening bracket on a separate line for several
intrinsics (for consistency with the rest of the intrinsics).
2. emmintrin.h - Moved the doxygen comment next to the body of the function;
- Added braces after extern "C" even though there is only
one declaration each time
3. xmmintrin.h - Moved the doxygen comment next to the body of the function;
- Added intrinsic prototypes for a couple of macro definitions
into the doxygen comment;
- Added braces after extern "C" even though there is only one
declaration each time
4. ammintrin.h – Removed extra line between the doxygen comment and the body
of the functions (for consistency with the rest of the files).
