This doesn't actually do any x8664 tests, since no "-i" lines match x8664.

You might want
  -i x8664,native

Or, if you're trying to mirror x8632, change the first two "-e" to "-i" (and
then change the last one after sandboxing is implemented).

I know. This is on purpose: if I enable them before pushing the nacl CL, then no
one will be able to make presubmit. :(

Not true.  It's been common practice in Subzero to have to update to tip-of-tree
LLVM as necessary, particularly for the bitcode reader work.  And both options
worked for me when I tested.  Please get this enabled as soon possible, before
someone (me) breaks it again...
