Takes the libhwasan library from LLVM and puts it into our source tree
excluding the build system files.

Tieing the source files into our build system is done in a later commit.

We have taken the libsanitizer library from the same SVN revision as
the other sanitizer libraries are taken from (SVN revision 368656 as
mentioned in libsanitizer/MERGE).
