Auto merge of #37318 - nnethercote:html5ever-more, r=nrc,eddyb

Avoid some allocations in the macro parser

These three commits reduce the number of heap allocations done when compiling rustc-benchmarks/html5ever-2016-08-25 by 20%, from 16.5M to 13.3M. This speeds up (debug) compilation of it with a stage1 compiler by about 7%.
