Several tests fail with -fupc-pts=struct

[PHHargrove]

This issue is a place-holder until I can collect more complete information.

It appears that clang-upc2c emits multiple forms of invalid code when passed -fupc-pts=struct, including at least assignments between the two structure types (phased and phaseless pts) and from these structs to scalar type(s).

When I have more time, I will follow up with specific tests names from the Berkeley suite and/or examples of the invalid code. I have taken assignment of the issue until I can provide the missing information, but I don't expect I have the ability to fix the issue(s).

At this point I believe every failure I am seeing on an x86-32 platform with -fupc-pts=struct is attributable to one of the four issues listed above. So, I am closing this issue.
