[ThinLTO] Add a recursive step in Metadata lazy-loading
Summary:
Without this, we're stressing the RAUW of unique nodes,
which is a costly operation. This is intended to limit
the number of RAUW, and is very effective on the total
link-time of opt with ThinLTO, before:
real 4m4.587s user 15m3.401s sys 0m23.616s
after:
real 3m25.261s user 12m22.132s sys 0m24.152s
