David Spickett 1db2d571b5 [llvm][TableGen] Fix misleading error for invalid use of let (#118616 )

Fixes #118490

Point to the value name, otherwise it implies that the part after the
'=' is the problem.

Before:
```
/tmp/test.td:2:27: error: Value 'FlattenedFeatures' unknown!
  let FlattenedFeatures = [];
                          ^
```
After:
```
/tmp/test.td:2:7: error: Value 'FlattenedFeatures' unknown!
  let FlattenedFeatures = [];
      ^
```
