[PATCH] parallelize g++ testing a bit more

[Nathan Froyd <nfroyd@mozilla.com>]

I've done a lot of g++-only testsuite runs lately and I noticed that it
didn't parallelize all that well.  The patch below adds a couple more
.exp files to the parallel infrastructure.  dg-torture.exp is the big
one; it takes about as much time as old-deja.exp.

Other valid candidates are lto.exp and debug.exp, but the patch cuts g++
testing time in half as-is, so I felt it was a sufficient stopping
point.

OK to commit?
