[Bug c++/17278] [4.0 Regression] 24% C++ compile-time regression in comparison with 3.4.1 at -O1 optimization level

It's interesting that -O1 is consistently slower than previous
releases.  Perhaps we should turn off some of the more costly
tree passes at -O1, such as iterating in DOM, and the expensive
loop optimizations.  Any thoughts on this?
