Yvan Roux 0e4827aa4e [ARM][MachineOutliner] Add Machine Outliner support for ARM. ...

Enables Machine Outlining for ARM and Thumb2 modes.  This is the first
patch of the series which adds all the basic logic for the support, and
only handles tail-calls and thunks.

The outliner can be turned on by using clang -moutline option or -mllvm
-enable-machine-outliner one (like AArch64).
