The test: Stage1 built -O2 by some random installed compiler.
	  Stage2 built with make CC='stage1/xgcc -B./stage1/' CFLAGS='-O0'

Results: mainline: 406.71user 43.96system 7:50.99elapsed 95%CPU
          patched: 457.22user 45.42system 8:42.63elapsed 96%CPU

So we cost about 11% more.  It doesn't seem serious to me, 
but I'll wait for an ok before checking it in.
