For now, this means using `//`-style comments in .c source files (though not public header files), and spaces rather than tabs. No strong opinion here; this is just what the majority of the current code is using. This also synchronizes basics/crt/crt1.c with libc-bottom-half's version, though this is just a cleanup as the former isn't currently used by the main wasi-libc build.
