[OpenCL] Add NULL to standards prior to v2.0.
NULL was undefined in OpenCL prior to version 2.0. However, the
language specification states that "macro names defined by the C99
specification but not currently supported by OpenCL are reserved
for future use". Therefore, application developers cannot redefine
NULL.
The change is supposed to resolve inconsistency between language
versions. Currently there is no apparent reason why NULL should
be kept undefined.

replaced with `//third_party/zlib` after template substitution. This will then
attempt to find `//third_party/zlib` within the local repository
`@llvm_zlib//third_party/zlib`, which does not exist, rather than the intended
reference back to the main repository. The issue appears to be that the
conversion of `Label` type to string with
`str(repository_ctx.attr.external_zlib)`, which is causing the main repository
qualifier to be lost.
This diff fixes the issue by changing the `external_zlib` attribute to
`attr.string` type rather than `attr.label`.
In future a more elegant solution may be possible that preserves use of the
`Label` type, depending on resolution of the issue

Fix the logic so stop-hooks get run after a breakpoint that ran an expression
Code was added to Target::RunStopHook to make sure that we don't run stop hooks when
you stop after an expression evaluation. But the way it was done was to check that we
hadn't run an expression since the last natural stop. That failed in the case where you
stopped for a breakpoint which had run an expression, because the stop-hooks get run
after the breakpoint actions, and so by the time we got to running the stop-hooks,
we had already run a user expression.
I fixed this by adding a target ivar tracking the last natural stop ID at which we had
run a stop-hook. Then we keep track of this and make sure we run the stop-hooks only
once per natural stop.

PR51158: Don't emit -Wswitch or -Wcovered-switch-default for empty enums
An empty enum is used to implement C++'s new-ish "byte" type (to make
sure it's a separate type for overloading, etc - compared to a typedef)
- without any enumerators. Some clang warnings don't make sense in this
sort of situation, so let's skip them for empty enums.
It's arguable that possibly some situations of enumerations without
enumerators might want the previous-to-this-patch behavior (if the enum
is autogenerated and in some cases comes up empty, then maybe a default
in an empty switch would still be considered problematic - so that when
you add the first enumeration you do get a -Wswitch warning). But I
think that's niche enough & this std::byte case is mainstream enough
that we should prioritize the latter over the former.
If someone's got a middle ground proposal to account for both of those
situations, I'm open to patches/suggestions/etc.

[SimplifyCFG] SimplifyCondBranchToTwoReturns(): really only deal with different ret blocks
This function is called when some predecessor of an empty return block
ends with a conditional branch, with both successors being empty ret blocks.
Now, because of the way SimplifyCFG works, it might happen to simplify
one of the blocks in a way that makes a conditional branch
into an unconditional one, since it's destinations are now identical,
but it might not have actually simplified said conditional branch
into an unconditional one yet.
So, we have to check that ourselves first,
especially now that SimplifyCFG aggressively tail-merges
all ret and resume blocks.
Even if it was an unconditional branch already,
`SimplifyCFGOpt::simplifyReturn()` doesn't call `FoldReturnIntoUncondBranch()`
by default.

[clang-tidy] performance-unnecessary-copy-initialization: Create option to exclude container types from triggering the check.
Add string list option of type names analagous to `AllowedTypes` which lets
users specify a list of ExcludedContainerTypes.
Types matching this list will not trigger the check when an expensive variable
is copy initialized from a const accessor method they provide, i.e.:
```
ExcludedContainerTypes = 'ExcludedType'
void foo() {
ExcludedType<ExpensiveToCopy> Container;
const ExpensiveToCopy NecessaryCopy = Container.get();
}
```
Even though an expensive to copy variable is copy initialized the check does not
trigger because the container type is excluded.
This is useful for container types that don't own their data, such as view types
where modification of the returned references in other places cannot be reliably
tracked, or const incorrect types.
