Tom Honermann 59019b4223 P0482R5 char8_t: Updates to existing standard library tests 
This patch augments existing tests to validate behavior for char8_t.  In
all cases, added test cases are cloned from existing tests for wchar_t
or char16_t.

A few tests required updates to line numbers for diagnostic messages.
