Where (backtrace) did the C_MAYBE_CONST_EXPR get created?  Where 
(backtrace) did the NOP_EXPR get created?  The tree going inside a 
C_MAYBE_CONST_EXPR should have been folded at the point the 
C_MAYBE_CONST_EXPR was created, though that is meant to be an efficiency 
issue (avoiding multiple folding of the same trees) rather than required 
to avoid ICEs.
