There is a decision between two options:
The difference is, that the second implies the amount of registers in the constraint, while the other one does not (or implies 1 if not stated otherwise).
And would clobbering a register with the constraint "G" imply that a register pair is clobbered (is this easy to implement in GCC/LLVM)?
Must start with an even-numbered register.
NOTE: This is NOT implemented on either on LLVM or GCC yet, this PR will hold until at least one compiler has implemented.
Fix #37
