18350af159 [gicombiner] Add a CodeExpander to handle C++ fragments with variable expansion
Summary:
This will handle expansion of C++ fragments in the declarative combiner
including custom predicates, and escapes into C++ to aid the migration
effort.

Fixed the -DLLVM_LINK_LLVM_DYLIB=ON using DISABLE_LLVM_LINK_LLVM_DYLIB when
creating the library. Apparently it automatically links to libLLVM.dylib
and we don't want that from tablegen.

2a964eabaa [gicombiner] Fix a nullptr dereference when -combiners is given a name that isn't defined
This is unlikely to be the root cause for the windows bot failures but
it would explain the stack trace seen.

505d7f3105 [gicombiner] Add the boring boilerplate for the declarative combiner
Summary:
This is the first of a series of patches extracted from a much bigger WIP
patch. It merely establishes the tblgen pass and the way empty combiner
helpers are declared and integrated into a combiner info.

The tablegen pass takes a -combiners option to select the combiner helper
that will be generated. This can be given multiple values to generate
multiple combiner helpers at once. Doing so helps to minimize parsing
overhead.

The reason for creating a GlobalISel subdirectory in utils/TableGen is that
there will be quite a lot of non-pass files (~15) by the time the patch
series is done.
