Fix for 5.5 Parameter Passing --> Stage C:
-- C.4 and C.5 statements, when NSAA is not equal to SP.
-- C.1.cp statement for VA functions. Note: There are no VFP CPRCs in a
variadic procedure.
Before this patch "NSAA != 0" means "don't use GPRs anymore ". But there are
some exceptions in AAPCS.
1. For non VA function: allocate all VFP regs for CPRC. When all VFPs are allocated
CPRCs would be sent to stack, while non CPRCs may be still allocated in GRPs.
2. Check that for VA functions all params uses GPRs and then stack.
No exceptions, no CPRCs here.
