Matthias Braun 744c215e29 TargetLowering: Add finalizeLowering() function; NFC ...

Adds a new method finalizeLowering to TargetLoweringBase. This is in
preparation for an upcoming commit.

This function is meant for target specific adjustments to
MachineFrameInfo or register reservations.

Move the freezeRegisters() and the hasCopyImplyingStackAdjustment()
handling into the new function to prove the concept. As an added bonus
GlobalISel no longer missed the hasCopyImplyingStackAdjustment()
handling with this.
