PPCRec: Unify BCCTR and BCLR code

Browse source 
Instead of having fixed macros for BCCTR/BCCTRL/BCLR/BCLRL we now have only one single macro instruction that takes the jump destination as a register parameter.
This also allows us to reuse an already loaded LR register (by something like MTLR) instead of loading it again from memory.

As a necessary requirement for this: The register allocator now has support for read operations in suffix instructions
