For PR1090:
Clean up the definitions of the helper functions per Chris' review
suggestions so they are easier to read.

For PR1091:
Print minimum signed integer values as unsigned so that we get no warnings
from the C compiler about constant ranges and value comparisons.

This test case needs zext and sext attributes so manually upgrade it and
don't run llvm-upgrade.

This test case has been translated to 2.0 assembly so don't run
llvm-upgrade on it.

This tests for something that will become illegal soon. The test/Feature
suite has a test for renaming of global variables.

Beef up this test case a little by introducing a global variable name
conflict after upgrade resulting from collapsed type planes. The test now
checks to make sure llvm-upgrade produces appropriate warning messages.

Make this test that we can drop the implementation keyword for llvm-as.
llvm-upgrade is irrelevant for this test case.

Fix the test case for the change in parameter attribute syntax. The @ is
no longer needed and the @(...) syntax has been dropped in favor of a
simple space separated list of attribute names.

For PR1077:
Split this test case into three cases. globalredefinition.ll just tests
that a global can be forward referenced. globalredefinition2.ll tests
that llvm-upgrade will warn about renaming duplicate global variables.
globalredefinition3.ll tests that llvm-as will generate an error on
duplicate global variables. This last test is currently XFAIL because
the restriction is not implemented yet.
