[WebAssembly] Simplify generation of "names" section Simplify generation of "names" section by simply iterating over the DefinedFunctions array. This even fixes some bugs, judging by the test changes required. Some tests are asserting that functions are named multiple times, other tests are asserting that the "names" section contains the function's alias rather than its original name Patch by Nicholas Wilson!
