Clang 19 now implements CWG 96 [1], which requires a template argument
list after a 'template' keyword, resulting in errors similar to:
/wrkdirs/usr/ports/devel/llvm13/work/llvm-project-13.0.1.src/flang/include/flang/Evaluate/integer.h:310:32:
error: a template argument list is expected after a name prefixed by the
template keyword [-Wmissing-template-arg-list-after-template-kw]
310 | auto back{FROM::template ConvertSigned(result.value)};
| ^
Upstream has committed a fix to their main branch [2], but it does not
apply cleanly to 13.0.1, so add a backported patch.
