DebugInfo: Add the name as-written, separate from the mangled name (#…

There's not much mangling happening yet - but Run -> main (and some
overloading numbering happening, maybe LLVM is doing that 'helpfully'
under the hood?) is enough to demonstrate this improvement/fix.

Ah, here it is:
```

#8  0x0000555558ce7bb5 in Carbon::Lower::FileContext::BuildFunctionDecl (this=0x7fffffffc438, function_id=...) at toolchain/lower/file_context.cpp:257
```

That's where LLVM decides to make a new name (name.number) when asked to
create a new global with the same name as an existing global.

It's not a valid mangling scheme - since the name won't be stable
between different compilations, but it is enough to make
single-compilation code build/run for now.
