Confirmed.

SCC consists of: MPT.765_6816(ab) ...[5000 others snipped]... code_6815
MPT.765_6793

Danny has some speedup ideas, apart from that you can tune
--parm sccvn-max-scc-size.  A value of 5000 shrinks compile-time to 2.4s.

With checking enabled and a much older version of 4.3.0:
 tree PRE  : 196.08 (97%) usr   2.78 (74%) sys 276.77 (97%) wall   
2434 kB (10%) ggc

While on the trunk we get:
 tree PRE  :   0.54 (12%) usr   0.02 ( 3%) sys   0.56 (11%) wall   
 573 kB ( 3%) ggc
