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

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1121 91177308-0d34-0410-b5e6-96231b3b80d8

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).

Added an assertion since it seems like AdjList returns an errornous size in method
IGNode::pushOnStack().

Avoid making a broken transformation!

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@1115 91177308-0d34-0410-b5e6-96231b3b80d8

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 ]
//
