perf symbols: Fix JIT symbol resolution on heap Gaurav reported that perf cannot profile JIT program if it executes the code on heap. This was because current map__new() only handle JIT on anon mappings - extends it to handle no_dso (heap, stack) case too. This patch assumes JIT profiling only provides dynamic function symbols so check the mapping type to distinguish the case. It'd provide no symbols for data mapping - if we need to support symbols on data mappings later it should be changed.
