- Introduce helper to push arguments onto the stack (Standalone this
change doesn't make a lot of sense, but is in preparation for including
the receiver in argc).
- Introduce helper to shift arguments already on the stack to make room
for new arguments (Varargs).
- arm64 is not included because a) there was already a helper similar
to ShiftArguments and b) PushArguments is not similar enough to make
sense for arm64 because of small differences (e.g. also pushing the
function) in conjunction with stack alignment.
