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.

Convert signed integer types to signless.

llvm-svn: 32790

Update the test suite to accommodate the change from signed integer types
to signless integer types. The changes were of only a few kinds:

1. Make sure llvm-upgrade is run on the source which does the bulk of the
   changes automatically.

2. Change things like "grep 'int'" to "grep 'i32'"

3. In several tests bitcasting caused the same name to be reused in the
   same type plane. These had to be manually fixed. The fix was (generally)
   to leave the bitcast and provide the instruction with a new name. This
   should not affect the semantics of the test. In a few cases, the
   bitcasts were known to be superfluous and irrelevant to the test case
   so they were removed.

4. One test case uses a bytecode file which needed to be updated to the
   latest bytecode format.

llvm-svn: 32789

Three changes:
1. Convert signed integer types to signless versions.
2. Implement the @sext and @zext parameter attributes. Previously the
   type of an function parameter was used to determine whether it should
   be sign extended or zero extended before the call. This information is
   now communicated via the function type's parameter attributes.
3. The interface to LowerCallTo had to be changed in order to accommodate
   the parameter attribute information. Although it would have been
   convenient to pass in the FunctionType itself, there isn't always one
   present in the caller. Consequently, a signedness indication for the
   result type and for each parameter was provided for in the interface
   to this method. All implementations were changed to make the adjustment
   necessary.
