Currently ppir continues compilation when there is an unsupported intrinsic, resulting in a shader that will surely not work as intended.
This is a problem during piglit runs as some tests don't compile properly due to this but actually still get submitted to the gpu and leave the system in an unstable state after executing, causing further tests to fail.
Also add a patch print names of unsupported intrinsics to help debugging and bug reporting like we do for nir_op.
