Add a test case for abstract parameter and result types in function
definitions. The assembler should produce an error on this input.

For PR1070:
Tweak the RUN: lines of these tests to accommodate the renaming of
variables done by llvm-upgrade. The renaming occurs as a result of avoiding
name collisons for collapsed type planes. Conflicting names have a .u
(unsigned) or .s (signed) suffix added. This patch updates the grep
expression to accommodate the new names.

For PR1070:
Revert previous patch now that llvm-upgrade can handle collapsed type
plane conversion properly.

Manually upgrade this test case to make sure that the new cast-to-bool
semantics are retained.

For PR1070:
Add a test case to ensure that llvm-upgrade retains correct semantics
for the previous definition of "cast to bool" which compared against null.

For PR1070:
Revise the upgrade parser to keep track of types more faithfully and use
this information to resolve name conflicts resulting from collapsed type
planes. The type planes have collapsed because the integer types are now
signless so that uint and int became i32. Where two planes existed for uint
and int, only i32 exists. Any variable names depending on the type planes
to pmake the identifier unique would cause a conflict. This patch resolves
that conflict for many but not all cases.

Situations involving the integer types and pointers to them are handled
by this patch.  However, there are corner cases that are not handled
well, such as:

%t1 = type { uint, int }
%t2 = type { int, uint }

void %myfunc(%t1* one, %t2* two) {
  %var = load %t1* one
  %var = load %t2* two
}

In the scenario above, %t1 and %t2 are really the same type: { i32, i32 }
Consequently attempting to name %var twice will yield a redefinition error
when assembled.

While this patch is sufficien to allow the llvm/test suite to pass, More
work needs to be to complete the handling of these corner cases.
