This attribute allows declarations to be restricted to the framework
itself, enabling Swift to remove the declarations when importing
libraries. This is useful in the case that the functions can be
implemented in a more natural way for Swift.

This code never actually did anything in the implementation.
`mergeDeclAttribute` is declared as `static`, and referenced exactly
once in the file: from `Sema::mergeDeclAttributes`.
`Sema::mergeDeclAttributes` sets `LocalAMK` to `AMK_None`. If the
attribute is `DeprecatedAttr`, `UnavailableAttr`, or `AvailabilityAttr`
then the `LocalAMK` is updated. However, because we are dealing with a
`SwiftNameDeclAttr` here, `LocalAMK` remains `AMK_None`. This is then
passed to the function which will as a result pass the value of
`AMK_None == AMK_Override` aka `false`. Simply propagate the value
through and erase the dead codepath.
Thanks to Aaron Ballman for flagging the use of the availability merge
kind here leading to this simplification!

Add the ability to selectively instrument a subset of functions by dividing the functions into N logical groups and then selecting a group to cover. By selecting different groups over time you could cover the entire application incrementally with lower overhead than instrumenting the entire application at once.

This reverts commit 8e780a1653e6f87755a447e921b8f929d8b70996.
DiagnosticBuilder is a value type, created on the stack everywhere. IMO
we should not be adding a vtable to it, and making very operator<< use a
virtual interface. There are other feasible designs for implementing
this. The original review, D84362, was approved by @tra, who is
responsible for Clang's CUDA support, but it wasn't reviewed by @rsmith
or anyone responsible for clang's diagnostic library.
Add the `swift_newtype` attribute which allows a type definition to be
imported into Swift as a new type. The imported type must be either an
enumerated type (enum) or an object type (struct).

This patch implements custom codegen for the vec_replace_elt and
vec_replace_unaligned builtins.
These builtins map to the @llvm.ppc.altivec.vinsw and @llvm.ppc.altivec.vinsd
intrinsics depending on the arguments. The main motivation for doing custom
codegen for these intrinsics is because there are float and double versions of
the builtin. Normally, the converting the float to an integer would be done via
fptoui in the IR. This is incorrect as fptoui truncates the value and we must
ensure the value is not truncated. Therefore, we provide custom codegen to utilize
bitcast instead as bitcasts do not truncate.

This introduces the new `swift_name` attribute that allows annotating
APIs with an alternate spelling for Swift. This is used as part of the
importing mechanism to allow interfaces to be imported with a new name
into Swift. It takes a parameter which is the Swift function name.
This parameter is validated to check if it matches the possible
transformed signature in Swift.

There can be Macros that are tagged with `modifiable`. Thus verifying
`canModifyAllDescendants` is not sufficient to avoid macros when deep
copying.
We think the `TokenBuffer` could inform us whether a `Token` comes from
a macro. We'll look into that when we can surface this information
easily, for instance in unit tests for `ComputeReplacements`.

No support for the new kinds of non-type template argument yet.

Instead of relying on whether a certain identifier is a builtin, introduce BuiltinAttr to specify a declaration as having builtin semantics.
This fixes incompatible redeclarations of builtins, as reverting the identifier as being builtin due to one incompatible redeclaration would have broken rest of the builtin calls.
Mostly-compatible redeclarations of builtins also no longer have builtin semantics. They don't call the builtin nor inherit their attributes.
A long-standing FIXME regarding builtins inside a namespace enclosed in extern "C" not being recognized is also addressed.
Due to the more correct handling attributes for builtin functions are added in more places, resulting in more useful warnings.
Tests are updated to reflect that.
Intrinsics without an inline definition in intrin.h had `inline` and `static` removed as they had no effect and caused them to no longer be recognized as builtins otherwise.
A pthread_create() related test is XFAIL-ed, as it relied on it being recognized as a builtin based on its name.
The builtin declaration syntax is too restrictive and doesn't allow custom structs, function pointers, etc.
It seems to be the only case and fixing this would require reworking the current builtin syntax, so this seems acceptable.
Fixes PR45410.

In CUDA/HIP a function may become implicit host device function by
pragma or constexpr. A host device function is checked in both
host and device compilation. However it may be emitted only
on host or device side, therefore the diagnostics should be
deferred until it is known to be emitted.
Currently clang is only able to defer certain diagnostics. This causes
false alarms and limits the usefulness of host device functions.
This patch lets clang defer all overloading resolution diagnostics for host device functions.
An option -fgpu-defer-diag is added to control this behavior. By default
it is off.
It is NFC for other languages.
