This is a script to build ISPC from scratch, including building patched version of LLVM.
NOTE THAT RELEASE VERSION OF ISPC MUST BE BUILT WITH PATCHED VERSION OF LLVM.

 Options:
  -v, --version       LLVM version to build with. ${llvm_version} is currently recommended.
  -h, --ispc_home     Path to ISPC HOME directory.
  -l, --llvm_dir      Path to use for LLVM build. ${llvm_dir} is default.
  -b, --ispc_build    Path to ISPC build directory. ${ispc_build} is default.
  -i, --ispc_install  Path to ISPC install directory. ${ispc_install} is default.
  -j, --speed         Number of threads for build. ${speed} is default.
  --help              Display this help and exit.
