get_results opcode used to fetch exception object

[allison]

The get_results opcode will no longer be used to fetch the exception object argument inside an exception handler. Instead, use the ordinary syntax for fetching a parameter (the .param declaration, or set_params).

Can't use .param in a block-style exception handler. Do you have some sample syntax you'd expect to see work?

It's my opinion that we should reject this ticket. Replacing .get_results with .param in these instances would be a lot of work: Significant effort in IMCC to replace the parsing of these ops, not to mention all the massive amounts of PIR that would need to get updated to use the new syntax. I think the benefits we get from the conversion are not worth the effort.

I agree. It's nice to have a consistent design, but not so nice that we need to rewrite a huge amount of existing PIR code and update imcc.
