f3b976e65f Convert backward conversion of expression trees into a new more powerful bidirectional approach. Add transforms for more instructions.

b7f06f46a1 Fixed instruction information for RDCCR and WRCCR.
Fixed selection to create a TmpInstruction for each integer CC register
(since it is an implicit side-effect, unlike FP CC registers which are
explicit operands).

5b497ee7c2 Add new cleanup pass:
//  1. PHI nodes with multiple entries for the same predecessor.  GCC sometimes
//     generates code that looks like this:
//
//  bb7:  br bool %cond1004, label %bb8, label %bb8
//  bb8: %reg119 = phi uint [ 0, %bb7 ], [ 1, %bb7 ]
//
//     which is completely illegal LLVM code.  To compensate for this, we insert
//     an extra basic block, and convert the code to look like this:
//
//  bb7: br bool %cond1004, label %bbX, label %bb8
//  bbX: br label bb8
//  bb8: %reg119 = phi uint [ 0, %bbX ], [ 1, %bb7 ]
//

b20807f23e * Export method to merge identically named methods
* Add code to fix PHI nodes that are missing arguments.  These PHI nodes can
  be generated by GCC if there is an uninitialized variable flowing into a merge
  point.  For example:

int foo(int y) {
  int X;
  if (y) X = 1;
  return X;
}

b6b26921e3 Add code to link method together with the same name if one is vararg and the other isn't.
This resolves definitions like this:
   %list * "foo"(...)
   %list * "foo"(int)

together which can often occur because C programmers don't put prototypes in like they should.  GRR

e99c66b74f * Add comments for peepholes
* Implement new peephole:
     // Peephole optimize the following instructions:
     // %t1 = cast {<...>} * %StructPtr to <ty> *
     //
     // Into: %t2 = getelementptr {<...>} * %StructPtr, <0, 0, 0, ...>
     //       %t1 = cast <eltype> * %t1 to <ty> *

  This peephole eliminated 9 evil casts in the health benchmark, and
  completely turned the addList method around.  :)

Needs to be bottom up because constant values may be forward-substituted

2. Move most of the constant-fixup code into machine-indepedent file
   InstrSelectionSupport.cpp.

0714e3bc44 Make the sparc.burg file be a little more flexible and rubust in the fact of
renumbering of instructions.  It is still horribly broken and grossly dependant on the number of instructions, but now it is a least a little better.

Oh yeah it also works now.

d05adbcdce Clean up parser, fix a bug that prevented this from working:
%ListNode3 = global %list { %list* null, int 4 }

because %list is name and the parser expected a literal {..} type there.

In addition, simplified rules that the fix (Allow any Types there, not just a StructType)
made obsolete.  Simplified type propogation a bit.

4cecdd206e Several fixes:
(1) Avoid hard-coding some register numbers.
(2) Fix some incorrect branch opcodes.
(3) Don't try to move int register to float register!
(4) If an operand being forwarded is a constant and it doesn't fit
    into the immed field of the copy machine instruction, then
    generate a load-constant instead of a copy.
(5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2".
