[PATCH] D57812: [ARM] Add OptMinSize Subtarget feature

[Sam Parker via Phabricator via llvm-commits]

Hi Florian,

The main motivations here are:

- remove the dependency of a MachineFunction on ARMSubtarget->useMovt so that we can query this function from ARMTTIImpl and other passes not using a MachineFunction.
- use the subtarget to enable us to perform different setOperationActions.
- use the subtarget to enable us to set different scheduling preferences.

cheers,
