Before emitting a warning message, code should check that the usage in question should be diagnosed by calling ShouldWarn(). A fair number of sites in the code do not, and can emit portability warnings unconditionally, which can confuse a user that hasn't asked for them (-pedantic) and isn't terribly concerned about portability *to* other compilers. Add calls to ShouldWarn() or IsEnabled() around messages that need them, and add -pedantic to tests that now require it to test their portability messages, and add more expected message lines to those tests when -pedantic causes other diagnostics to fire.
