LOG: [PhaseOrdering] move an 'opt' test from x86 codegen; NFC
This file comes from 2007, and I'm not entirely sure of the
motivation, but it was going through all of opt and llc.
The llc part is almost certainly unnecessary as shown in
the now auto-generated FileCheck lines.
This test may be affected by a logic change suggested in:
D87835
Added:
llvm/test/Transforms/PhaseOrdering/nancvt.ll
