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.

As a preparation step for fast8 support, we need to update the tests
to pass in both modes. That requires generalizing the shadow width
and remove any hard coded references that assume it's always 2 bytes.

new call has extra parameters. The attributes on parameters must be
updated to take the new position of each parameter into account.
