In PowerPC ABI, a few initial arguments are passed through registers, but their places in parameter save area are reserved, arguments passed by memory goes after the reserved location.
For debugging purpose, we may want to save copy of the pass-by-reg arguments into correct places on stack. The new option achieves by adding new function level attribute and make argument lowering part aware of it.

Subject: [PATCH] [AIX] Add -msave-reg-params to save arguments to stack
In PowerPC ABI, a few initial arguments are passed through registers,
but their places in parameter save area are reserved, arguments passed
by memory goes after the reserved location.
For debugging purpose, we may want to save copy of the pass-by-reg
arguments into correct places on stack. The new option achieves by
adding new function level attribute and make argument lowering part
aware of it.
