RegisterPressure: Expose RegisterOperands API
Previously the RegisterOperands have only been used internally in
RegisterPressure.cpp. However this datastructure can be useful for other
tasks as well and allows refactoring of PDiff initialisation out of
RPTracker::recede().
This patch:
- Exposes RegisterOperands as public API
- Splits RPTracker::recede() into a part that skips DebugValues and
maintains the region borders, and the core that changes register
pressure when given a set of RegisterOperands.
- This allows to move the PDiff initialisation out recede() into a
method of the PressureDiffs class.
- The upcoming subregister scheduling code will also use
RegisterOperands to avoid pushing more unrelated functionality into
recede()/advance().
