Auto merge of #30945 - nagisa:mir-optional-block-dest, r=nikomatsakis
As an attempt to make loop body destination be optional, author implemented a pretty self contained
change and deemed it to be (much) uglier than the alternative of just keeping the unit temporary.
Having the temporary created lazily also has a nice property of not figuring in the MIR of
functions which do not use loops of any sort.

r? @nikomatsakis
