Richard Smith 933a42da48 Move Itanium demangler implementation into a header file and add visitation support. ... Summary: This transforms the Itanium demangler into a generic reusable library that can be used to build, traverse, and transform Itanium mangled name trees. This is in preparation for adding a canonicalizing demangler, which cannot live in the Demangle library for layering reasons. In order to keep the diffs simpler, this patch moves more code to the new header than is strictly necessary: in particular, all of the printLeft / printRight implementations can be moved to the implementation file. (And indeed we could make them non-virtual now if we wished, and remove the vptr from Node.) All nodes are now included in the Kind enumeration, rather than omitting some of the Expr nodes, and the three different floating-point literal node types now have distinct Kind values. As a proof of concept for the visitation / matching mechanism, this patch implements a Node dumping facility on top of it, replacing the prior mechanism that produced the pretty-printed output rather than a tree dump. Sample dump output: FunctionEncoding( NameType("int"), NameWithTemplateArgs( NestedName( NameWithTemplateArgs( NameType("A"), TemplateArgs( {NameType("B")})), NameType("f")), TemplateArgs( {NameType("int")})), {}, <null>, QualConst, FunctionRefQual::FrefQualLValue) As a next step, it would make sense to move the LLVM high-level interface to the demangler (the itaniumDemangler function and ItaniumPartialDemangler class) into the Support library, and implement them in terms of the Demangle library. This would allow the libc++abi demangler implementation to be an identical copy of the llvm Demangle library, and would allow the LLVM implementation to reuse LLVM components such as llvm::BumpPtrAllocator, but we'll need to decide how to coordinate that with the MS ABI demangler, so I'm not doing that in this patch. No functionality change intended other than the behavior of dump().
