Before d08bd13ac8a560c4645e17e192ca07e1bdcd2895, only `SymbolRef::ST_Function` symbols were used for .symtab symbolization. That commit added a `"DATA"` mode to llvm-symbolizer which used `SymbolRef::ST_Data` symbols for symbolization. Since function and data symbols have different addresses, we don't need to differentiate the two modes. This patches unifies the two modes to simplify code. `"DATA"` is used by `compiler-rt/lib/sanitizer_common/sanitizer_symbolizer_libcdep.cpp`. `check-hwasan` and `check-tsan` have runtime tests.

## Function and data symbols have different addresses so internally we treat
|
|
## STT_NOTYPE/STT_FUNC/STT_DATA/etc the same. The DATA command may get a function
|
|
## as result. For regular applications, the input addresses are guaranteed to be
|
|
## related to data symbols.
