This patch extends the `FIRToLLVMLowering` pass in Flang by adding a
hook to transform `fir.coordinate_of` into a sequence of LLVM MLIR
instructions.

The following cases are currently supported:

1. the input object is a `fir.complex` (wrapped in e.g. `fir.ref` or `fir.box`)
2. the input object is wrapped in a `fir.box` (including e.g. `fir.array`).

Note that `fir.complex` wrapped in a `fir.box` falls under case 1. above
(i.e. it's a special case regardless of the wrapping type). Sequence
types are not yet supported (e.g. `fir.array` that is _not wrapped_ with
`fir.box`).

This is part of the upstreaming effort from the `fir-dev` branch in [1].
