Establish a set of optional usage warnings, and enable some only in "-pedantic" mode that, in our subjective experience with application codes, seem to issue frequently without indicating usage that really needs to be corrected. By default, with this patch the compiler should appear to be somewhat less persnickety but not less informative. Differential Revision: https://reviews.llvm.org/D150710
