3*9880d681SAndroid Build Coastguard Worker; Previously we would forget to align to stack slot alignment after placing a
4*9880d681SAndroid Build Coastguard Worker; byval argument.  Subsequent arguments would align themselves, but if it was
5*9880d681SAndroid Build Coastguard Worker; the last argument, the argument size would not be a multiple of stack slot
6*9880d681SAndroid Build Coastguard Worker; size. This resulted in retl $6 in callee-cleanup functions, as well as subtle
7*9880d681SAndroid Build Coastguard Worker; varargs bugs.
