ccac6e36fb I can't believe the incompetence of the people I have to deal with around here. 
These fools don't even wrap code at 80 columns.

Oh wait, _I_ wrote that.  That explains a lot!!

0ba2cec700 Fix PR 110: the constant folding code assumes that if something is not a 
constant expression, but is of (for example) ubyte type, then it is a
ConstantUInt.  This was not true for placeholders.

d966bbe9bf 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.)

58f9d30da4 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.

fbd3f16961 PreSelection is not optional, it performs a necessary and vital transformation 
for the Sparc backend: breaking up constant expressions. Thus, we cannot have it
guarded by a conditional, it should never be disabled.

Also, it's now available for the JIT since it is a FunctionPass.

c6a7c83333 Change all machine basic block modifier functions in MRegisterInfo to 
return the number of instructions added to/removed from the basic block
passed as their first argument.

Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.

Added assert() to ensure symbol table is well formed.
Added code to remember the value that was found; resolving types can change
