codegen: modernize frame-pointer-cli-control.rs

Browse Source 
Update this time-traveler on the changes in compiletest and target specs
that they missed over the pass ~3 years by being caught in a time rift.
The aarch64-apple rev splits into itself and aarch64-apple-on, because
rustc obtained support for non-leaf frame-pointers ever since 9b67cba
implemented them and used them in aarch64-apple-darwin's spec.

Note that the aarch64-apple-off revision fails, despite modernization.
This is because 9b67cba also changed the behavior of rustc to defer to
the spec over the command-line interface.
