[llvm-cxxfilt] Add --quote option to quote demangled function names (#111871)
This is useful when looking at LLVM/MLIR assembly produced from C++
sources. For example
cir.call @_ZN3aie4tileILi1ELi4EE7programIZ4mainE3$_0EEvOT_(%2, %7) :
will be translated to
cir.call @"void aie::tile<1, 4>::program<main::$_0>(main::$_0&&)"(%2,
%7) : which can be parsed as valid MLIR by the right mlir-lsp-server.
If a symbol is already quoted, do not quote it more.
