<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Bignum: add support for negative shifts (fix #18499)

shiftR/shiftL support negative arguments despite Haskell 2010 report

saying otherwise. We explicitly test for negative values which is bad

(it gets in the way of constant folding, etc.). Anyway, for consistency

we fix Bits instancesof Integer/Natural.
