Codespaces - ISPC developer's environment (CPU only)

This is the minimal environment that enables CPU-only ISPC build (i.e. GPU backend is not enabled).

To build ISPC and run the tests do the following:

# `build` folder already contains result of `cmake .. -DCMAKE_EXPORT_COMPILE_COMMANDS=ON`
cd build
# build ISPC and examples
make -j4
# run LIT tests
make check-all
# run functional tests
cd /workspaces/ispc
PATH=`pwd`/build/bin:$PATH ./scripts/run_tests.py --target=avx2-i32x4

Note that build folder already contains compile_commands.json, which is needed for VSCode to be able correctly parse and browse C++ files.

The container also contains pre-installed C/C++ Extension Pack for VSCode.
