ff11026575 - Added MRegisterInfo::getCrossCopyRegClass() hook. For register classes where reg to reg copies are not possible, this returns another register class which registers in the specified register class can be copied to (and copy back from). 
- X86 copyRegToReg() now supports copying between EFLAGS and GR32 / GR64 registers.

46abf91f73 Added C and Ocaml bindings for functions, basic blocks, and 
instruction creation. No support yet for instruction introspection.

Also eliminated allocas from the Ocaml bindings for portability,
and avoided unnecessary casts.

a37c9f7506 When both x/y and x%y are needed (x and y both scalar integer), compute 
both results with a single div or idiv instruction. This uses new X86ISD
nodes for DIV and IDIV which are introduced during the legalize phase
so that the SelectionDAG's CSE can automatically eliminate redundant
computations.

0488db9b99 Added support for new condition code modeling scheme (i.e. physical register dependency). These are a bunch of instructions that are duplicated so the x86 backend can support both the old and new schemes at the same time. They will be deleted after 
all the kinks are worked out.
