hugolib: Add site building benchmarks
To run a subset of these benchmark, one can do something like this: ``` go test -run="NONE" -bench="BenchmarkSiteBuilding/tags_per_page=0.*shortcodes=true.*render=false" -test.benchmem=true ./hugolib ``` Which will run without any tags, with shortcodes, but will skip rendering. Fixes #3535

Use 3 dashes for an em-dash. Use 2 dashes for ranges (ex., "it's all

in chapters 12--14"). Three dots ... will be converted to an ellipsis.
