If the former, indicate that GPR registers are needed,

Also look for LHS = (*ptr).field, where ptr is one of the forms
listed above.
On alpha, cfun->va_list_gpr_size is used as size of the needed
regs and cfun->va_list_fpr_size is a bitmask, bit 0 set if
GPR registers are needed and bit 1 set if FPR registers are needed.
