The long awaited CAST patch. This introduces 12 new instructions into LLVM to replace the cast instruction. Corresponding changes throughout LLVM are provided. This passes llvm-test, llvm/test, and SPEC CPUINT2000 with the exception of 175.vpr which fails only on a slight floating point output difference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31931 91177308-0d34-0410-b5e6-96231b3b80d8
