[TableGen] Indentation and whitespace fixes in generated code. NFC.

[foad]

Summary

Some of these were found by running clang-format over the generated
code, although that complains about far more issues than I have fixed
here.

[Paul-C-Anagnostopoulos]

LGTM.

But what is "NFC"?

No functional change! Or sometimes NFCI for no functional change intended, if you're feeling doubtful.

Duly added to my initialism list.
