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.

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.

Update for signless integer types:
1. Replace [us]byte with i8
2. Replace [u]short with i16
3. Replace [u]int   with i32
4. Replace [u]long  with i64
5. Document the "define" keyword and use it in all examples.
6. Document parameter attributes and how they affect function types.
