If translation units that use thread local variables are built with
LTO (using native TLS, not emulated TLS), then the implicit access
to _tls_index isn't visible on the LTO object file level.
Therefore, mark _tls_index as used, so that it gets retained through
LTO.
This fixes linking user code with LTO, if the base CRT files also
are built with LTO enabled.
This is similar to 7ef0ba478f664a78a8509c81d5e40a34e821ac8c which
marked _tls_used as used too.
