We're missing out on handling an explicit `-mtp=auto` here. While rare I think
it is worth matching gcc.
I think this could be done with changing
```
if (Arg *A = Args.getLastArg(options::OPT_mtp_mode_EQ))
```
To
```
Arg *A = Args.getLastArg(options::OPT_mtp_mode_EQ);
if (A && A->getValue() != "auto") {
...
}
return (isHardTPSupported(Triple) ? ReadTPMode::TPIDRURO : ReadTPMode::Soft);
