New which_grepl_linter

[MichaelChirico]

Part of #884

No hits on {lintr} itself.

LGTM. What do you think about introducing a regex_linter() that can support multiple lints, e.g. from fixed_regex_linter()?
It would allow future regex related lints to be automatically added to projects that opt into regex_linter(), reducing maintenance burden on .lintr.

[MichaelChirico]

There's two avenues we've used for this, one is to have a single linter that handles a lot of things (paste_linter() is quintessential here), the other is using tags. I prefer the latter in most cases -- adding lots of parameters for turning certain lints on/off within a linter is somewhat painful for maintenance.

[AshesITR]

SGTM. Should we add a tag "regex", then?
