[6/7] Random tweaks

This tweaks a few tests so that we don't have to skip them.  This is 
mostly concerned with declaring main properly, or changing other 
declarations where the test does not seem to rely on the type mismatches.

I've also included one example of changing a function name to not be 
"call", ptxas seems to have a bug that makes it not allow this function 
name. If that doesn't seem too awful I'll have a few more tests to fix 
up in this way.

There'll be a 7th patch, not because I can't count, but because I didn't 
follow a consistent naming scheme for the patches.
