This adds support for lowering more than 4 arguments (although still i32 only).
It uses the handleAssignments / ValueHandler infrastructure extracted from
the AArch64 backend in https://reviews.llvm.org/D27045 *.

- I can split out the part that is NFC with regard to https://reviews.llvm.org/D26677 (using ValueHandler

for <= 4 args).
