Seems partially fixed now.  It takes 19 minutes to compile, though. But!
it doesn't use more than 300Mb of core now.

$ /usr/bin/time gcc/cc1plus -ftemplate-depth-80 -fno-exceptions -Drestrict=__restrict__ -DNOPAssert -DNOCTAssert -O2 -march=athlon -funroll-loops -fomit-frame-pointer --param min-inline-insns=200 -quiet FieldCentering.cmpl.ii               1106.46user 1.19system

In contrast, this uses 200Mb of core in mainline and takes 17 seconds to
compile.  I'm thinking this and Gerald's PR8361 are good test cases :)
