test_ase FPEs with SDC

[zingale]

Build test_ase with

make USE_SIMPLIFIED_SDC=TRUE -j 4

then run as:

./main3d.gnu.ex inputs_ase amrex.fpe_trap_invalid=1

and we get and FPE right before the final NSE check

The problem is that we're not fully consistent with using X for strang and rhoX for sdc. I think I'm gonna change everything to rhoX since we have #1542

[zingale]

okay great. Indeed, I was hitting this as I was looking at #1542
