environment: search for icl and ifort before cl and goftran

Intel helpfully provides a cl.exe that is indistinguishable from
Microsoft's cl.exe in output, but has the same behavior as icl.exe.
Since icl and ifort will only be present in your path if you've started
an Intel command prompt search for that first.
