[NFC][TargetParser] Replace uses of llvm/Support/Host.h

The forwarding header is left in place because of its use in
`polly/lib/External/isl/interface/extract_interface.cc`, but I have
added a GCC warning about the fact it is deprecated, because it is used
in `isl` from where it is included by Polly.

[ASTMatchers] Output currently processing match and nodes on crash

Create a PrettyStackTraceEvent that will dump the current `MatchCallback` id as well as the `BoundNodes` if the 'run' method of a `MatchCallback` results in a crash.
The purpose of this is sometimes clang-tidy checks can crash in the `check` method. And in a large codebase with alot of checks enabled and in a release build, it can be near impossible to figure out which check as well as the source code that caused the crash. Without that information a reproducer is very hard to create.
This is a more generalised version of D118520 which has a nicer integration and should be useful to clients other than clang-tidy.

Remove clang::ast_type_traits namespace in favor of clang

DynTypedNode and ASTNodeKind are implemented as part of the clang AST
library, which uses the main clang namespace. There doesn't seem to be a
need for this extra level of namespacing.

I left behind aliases in the ast_type_traits namespace for out of tree
clients of these APIs. To provide aliases for the enumerators, I used
this pattern:
namespace ast_type_traits {
constexpr TraversalKind TK_AsIs = ::clang::TK_AsIs;
}
I think the typedefs will be useful for migration, but we might be able
to drop these enumerator aliases.

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
