    Add the Float32X4# primitive type and associated primops.
    
    This patch lays the groundwork needed for primop support for SIMD vectors. In
    addition to the groundwork, we add support for the FloatX4# primitive type and
    associated primops.
    
     * Add the FloatX4# primitive type and associated primops.
     * Add CodeGen support for Float vectors.
     * Compile vector operations to LLVM vector operations in the LLVM code
       generator.
     * Make the x86 native backend fail gracefully when encountering vector primops.
     * Only generate primop wrappers for vector primops when using LLVM.
