f30d47c518 aco: fix emitting TCS epilogs end on GFX9+ 
With merged shaders, the long-jump should be emitted inside the
divergent if (ie. only for TCS invocations) and other non TCS
invocations should just end the program.

This fixes a bunch of failures with CTS by forcing TCS epilogs on
RDNA2.

Not sure how RadeonSI will handle that but maybe doing the merged
wave info thing in epilogs would help.

65b6ac8aa4 nir: Rename nir_instr_type_ssa_undef to nir_instr_type_undef 
We already renamed the type, we just need to rename the enum and the
casting helper functions.

Generated with sed:

    sed -i -e 's/nir_instr_type_ssa_undef/nir_instr_type_undef/g' src/**/*.h src/**/*.c src/**/*.cpp
    sed -i -e 's/nir_instr_as_ssa_undef/nir_instr_as_undef/g' src/**/*.h src/**/*.c src/**/*.cpp

and two tiny whitespace fixups in lima.
