trsv: workaround intel/19.0.4 interal compiler error

[ndellingwood]

addresses issue #607 reported by Mike Glass
replace /= compound assignment operators

[ndellingwood]

I verified this worked with the previously failing configuration using the intel/19.0.4 module and the sierra-devel module environments.

Trilinos patch submitted in PR trilinos/Trilinos#6858

[mhoemmen]

I wrote this code, long ago. In fact, I think I generated it from a Python script.
