The XRebox Op is formed by the codegen rewrite which makes it easier to
convert the operation to LLVM. The XRebox op includes the information
from the rebox op and the associated slice, shift, and shape ops.
During the conversion process a new descriptor is created for reboxing.

For unimplemented patterns we revert to using TODO hard failures instead of
notifyMatchFailure.
For fir.select_type revert to using mlir::emiterror.
For the fir.embox TODO on a type with len params we cannot add a test since the type cannot be converted to llvm.
Adding negative tests using not and checking for the error message.
TODO exits with an error in a build without assertion but aborts in a
build with assertions. Abort requires using not with the --crash
option. The two different usages of not is handled by using a custom
command %not_todo_cmd which is converted to not or not --crash
depending on the presence or absence of assertions. Using llvm-config
to check the presence of assertions.

Some header `#include`s that belong in TypeConverter.h rather than in
CodeGen.cpp are moved accordingly. As TypeConverter.h is currently only
used in CodeGen.cpp, this wouldn't cause any build issues (ultimately,
all the required headers are included). However, this would become a problem
when including TypeConverter.h elsewhere.
Also, from [1], "(...) include all of the header files that you are
using ". This is currently not the case in TypeConverter.h and hence the
`#include`s should be moved.
I've also added missing namespace qualifiers in a few places in
TypeConverter.h
