lib: skip parsing invalid source maps
When the source map data are invalid json strings, skip construct
SourceMap on it. Additionally, suppress exceptions on source map lookups
and fix test runners crash on invalid source maps.
lib: optimize prepareStackTrace on builtin frames
Only invalidates source map lookup cache when a new source map is found.
This improves when user codes interleave with builtin functions, like
array.map
