clang-p2996/llvm/test/CodeGen/AArch64/fdiv.ll
David Green 58a2f839fd [AArch64][GISel] Expand coverage of FDiv and move into place. 
This adds some more extensive test coverage for fdiv through global isel,
switching the opcodes to use the more complete ActionDefinitions to handle more
cases and moving it into the position of the existing code which is no longer
needed.
