Implement a small optimization to handling of GEP's that are equivalent to casts.

This results in substantially reduced collapsing for some testcases

constant expression, but is of (for example) ubyte type, then it is a
ConstantUInt. This was not true for placeholders.

Change LLI's internal representation of va_list to a pointer to the next

argument to be returned by va_arg. This allows va_lists to be passed
between different LLVM procedures (though it is unlikely that an LLI
va_list would make sense to an external function, except by chance.)

Substantially re-organized this file:
...
* There is now only one pass to print out assembly instead of two
* It is a FunctionPass
* The Module-level printing of globals is now in doFinalization() method of the
FunctionPass
* The code has been reformatted to follow LLVM coding standards
* Some comments, not all, were doxygenified
* Last but not least, the function to create an instance of this pass is also no
longer a method in the UltraSparc class.
