Auto merge of #38733 - sfackler:peek-mut-pop, r=alexcrichton
Add PeekMut::pop A fairly common workflow is to put a bunch of stuff into a binary heap and then mutate the top value until its empty. This both makes that a bit more convenient (no need to save a boolean off and pop after to avoid borrowck issues), and a bit more efficient since you only shift once. r? @alexcrichton cc @rust-lang/libs
