There's some subtle interaction between inferred expressions being
passed as an argument to fn calls with fewer than expected arguments. To
avoid the ICE, I'm changing indexing operations with .get(idx), but
the underlying logic still needs to be audited as it was written with
the assumption that final_arg_types and provided_args have the right
length.

Address #96638.

r=me, but I wonder if we should see if someone wants to fix the root cause of the issue soon/first? I definitely think that if this lands, it should be reverted along with the actual fix for #96638

@jackh726 let's call that out in the ticket itself and land this in the meantime to avoid the ICE.
