[TableGen] Don't use inline storage for ReferenceLocs (NFC)

[nikic]

The ReferenceLocs are not enabled by default (they are used by the tablegen lsp server), and as such always empty, but still allocate inline storage for the SmallVector. Disabling it saves about 200MB on RISCVGenGlobalISel.inc.

(The equivalent field in Record already disables inline storage.)
