auto merge of #20786 : brson/rust/rustdocwarnings, r=huonw

Because we are warning about unstable APIs and there are many
of these yet, this creates a high likelyhood doc tests will
fail.

This doesn't seem right as a blanket policy to me anyway, though
certainly we want it in std. Probably more appropriate to add
a rustdoc option.
