Add initial files. This populates the repo with a very minimal set of files. This is just enough to set out a basic outline. Hopefully as we move forward we'll be replacing many of these parts, but this is just something basic to get things started. This tree isn't really usable yet, as it doesn't yet have an easy way to obtain a compiler-rt/libgcc build.

Update to musl 1.1.22. Most of the changes are in threads, TLS, dynamic linking, and other features wasi doesn&#39;t yet use, but there are some bug fixes in code wasi does use. atanl.c - local changes no longer needed as they&#39;ve now landed upstream. include/alltypes.h.in - Upstream now makes FILE a complete type in pre-C11 mode. For WASI, this level of pre-C11 strictness isn&#39;t as important, and having multiple incompatible definitions of _IO_FILE that are kept separate only by clever use of translation unit boundaries can confuse some tools, so stick with the incomplete type.
