Log:<br>
[TLI] Add prototype checking for all remaining LibFuncs.<br>
<br>
This is another step towards unifying all LibFunc prototype checks.<br>
This work started in r267758 (D19469); add the remaining checks.<br>
<br>
Also add a unittest that checks each libfunc declared with a known-valid<br>
and known-invalid prototype. New libfuncs added in the future are<br>
required to have prototype checking in place; the known-valid test will<br>
fail otherwise.<br>
