When used, these targets end up with calls to undefined functions for all of the various special vector stuff ispc needs to compile ispc programs (masked store, gather, min/max, sqrt, etc.). These targets are not yet useful for anything, but are a step toward having an option to C++ code with calls out to intrinsics. Reorganized the directory structure a bit and put the LLVM bitcode used to define target-specific stuff (as well as some generic built-ins stuff) into a builtins/ directory. Note that for building on Windows, it's now necessary to set a LLVM_VERSION environment variable (with values like LLVM_2_9, LLVM_3_0, LLVM_3_1svn, etc.)
