Changed this back to the original check which was clearer and easier for the 
reader to grok.

We are checking two distinct things here, so be explicit.  First, we check to 
see if the modules changed, e.g., from say from 'google' to 'modernize', then 
we check to see if the new module is 'llvm' and needs special handling.

Then, and only then, do we need to set the new_namespace variable, and we 
condition that on whether or not the new module name is 'llvm'.

+new_namespace = new_module

 check_implementation_files = glob.glob(

Why `new_namespace == 'llvm_check'` is needed? Can we figure out old_namespace 
and use the condition `new_namespace != old_namespace` instead?

Not sure it matters, but args.old_check_name is all lower case, so we have to 
uppercase the entire string.

I have another suggestion re: the color of this bike shed, namely: 
`llvm_checks`. But I don't feel strongly about this.

I'd add an explanation: `# Map module names to namespace names that don't 
conflict with widely used top-level namespaces.`

And again, no need to mention `clang` here.

I believe, we should first construct the new namespace name (using exactly the 
same code as in add_new_check.py) and then check if it differs from the old one.

No problem.  Or we could outlaw it...

We don't have the `clang` module. No need to check for it here. If we ever add 
one (which I doubt), we can modify this script again. But for now let's remove 
this to avoid confusion.

`--`?

Anyways, we don't have (or plan to have) a module named `clang`.

Just typo on my part.  I the options mentioned before where things like 
`llvm_project` or `llvm_proj`, etc.  I just settled on `llvm_check` because it 
sounded better -- then actually typed `checker`.  

I'll fix it this afternoon.
