Delete cpp.group_arguments (#49043)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/49043
Previously, this function had nontrivial algorithmic content,
but after #48195, this was just a swiss army knife for pasting
together arguments while maintaining structure. I added some
more properties for Arguments for convenient access in this way,
and then inlined the implementation of group_arguments into all of its call
sites, simplifying whenever contextual. This might be controversial, but I
think the resulting code is easier to understand.
You may notice that there is some modest code duplication between
dispatcher.cpparguments_exprs and CppSignature.argument_packs.
This is a known problem and I will be attempting to fix it in
a follow up PR.
Confirmed to be byte-for-byte compatible.
