Warn if kernel/fence does not have a name

[DavidPoliakoff]

This one shouldn't be too bad, something to the effect of

match callExpr(callee(functionDecl(namedDecl(matchesName("name_we_care_about")))),unless(hasAnyArgument(isStringish)))

Or I guess you could match the types of the parameters

match callExpr(callee(functionDecl(namedDecl(matchesName("name_we_care_about")),unless(hasAnyParameter(isStringish)))))

Guarantee that within Kokkos we name all of our kernels and fences
