T re warnings 20201214

[jkeenan]

This p.r. request cleans up all warnings in t/re/*.t with the exception of t/re/reg_mesg.t. The latter file already has a lot of tests of the text of warnings but in certain places turns warnings off. I'm corresponding with @khwilliamson about how to proceed with that file.

Otherwise, this p.r. should be reviewed so we can merge it.

For: #311

Thank you very much.

t/re/pat_psycho.t still has a warnings line that can be removed.

Are you sure? I'm not getting anything in that file.
