* fix minor bug with taking datasize of unsized array type

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

llvm-svn: 1121

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).

//  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 ]

* 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;
}
