The current naming scheme adds the `dfs$` prefix to all
DFSan-instrumented functions. This breaks mangling and prevents stack
trace printers and other tools from automatically demangling function
names.
This new naming scheme is mangling-compatible, with the `.dfsan`
suffix being a vendor-specific suffix:

With this fix, demangling utils would work out-of-the-box.
