This patch replaces RuntimeDyld::SymbolInfo with JITSymbol: A symbol class that is capable of lazy materialization (i.e. the symbol definition needn't be emitted until the address is requested). This can be used to support common and weak symbols in the JIT (though this is not implemented in this patch). For consistency, RuntimeDyld::SymbolResolver is renamed to JITSymbolResolver. For space efficiency a new class, JITEvaluatedSymbol, is introduced that behaves like the old RuntimeDyld::SymbolInfo - i.e. it is just a pair of an address and symbol flags. Instances of JITEvaluatedSymbol can be used in symbol-tables to avoid paying the space cost of the materializer. llvm-svn: 277386
