FYI: putting another pass_cprop_hardreg after pass_reorder_blocks fails
self-test with:
cc1: internal compiler error: pass cprop_hardreg does not support cloning
0x226f97d internal_error(char const*, ...)
../../git/gcc/gcc/diagnostic-global-context.cc:787
0xce6a79 opt_pass::clone()
../../git/gcc/gcc/passes.cc:90
