An irreducible SCC is one which has multiple "header" blocks, i.e., blocks with control-flow edges incident from outside the SCC. This pass converts an irreducible SCC into a natural loop by introducing a single new header block and redirecting all the edges on the original headers to this new block. This is a useful workaround for a limitation in the structurizer which, which produces incorrect control flow in the presence of irreducible regions. The AMDGPU backend provides an option to enable this pass before the structurizer, which may eventually be enabled by default.
