[PATCH] D39882: [clangd] Filter completion results by fuzzy-matching identifiers.

[Sam McCall via Phabricator via cfe-commits]

sammccall created this revision.

This allows us to limit the number of results we return and still allow them
to be surfaced by refining a query (https://reviews.llvm.org/D39852).

The initial algorithm is very conservative - it accepts a completion if the
filter is any case-insensitive sub-sequence. It does not attempt to rank items
based on match quality.
