Ilya Biryukov 295c8e1e2d [clangd] Always use preamble (even stale) for code completion
Summary:
This improves performance of code completion, because we avoid stating
the files from the preamble and never attempt to parse the files
without using the preamble if it's provided.

However, the change comes at a cost of sometimes providing incorrect
results when doing code completion after making actually considerable
changes to the files used in the preamble or the preamble itself.
Eventually the preamble will get rebuilt and code completion will
be providing the correct results.

Sam McCall 0faecf0c33 [clangd] Merge results from static/dynamic index.
Summary:
We now hide the static/dynamic split from the code completion, behind a
new implementation of the SymbolIndex interface. This will reduce the
complexity of the sema/index merging that needs to be done by
CodeComplete, at a fairly small cost in flexibility.

Sam McCall 3d139c527b [clangd] Code completion uses Sema for NS-level things in the current file.
Summary:
To stay fast, it avoids deserializing anything outside the current file, by
disabling the LoadExternal code completion option added in r322377, when the
index is enabled.

Haojian Wu ba28e9ac5d [clangd] Add static index for the global code completion.
Summary:
Use the YAML-format symbols (generated by the global-symbol-builder tool) to
do the global code completion.
It is **experimental** only , but it allows us to experience global code
completion on a relatively small project.

Tested with LLVM project.

Ilya Biryukov f60bf347c9 [clangd] Remove duplicates from code completion
Summary:
This patch removes hidden items from code completion.
Items can be hidden, e.g., by other items in the child scopes.
This patch addresses a particular problem of a duplicate completion
item for the class in the following example:

    struct Adapter { void method(); };
    void Adapter::method() {
       Adapter^
    }

We should probably investigate if there are other duplicates in
completion and remove them, possibly adding assertions that it never
happens.

Summary:

Deliberately resisted cleaning up much here, so this is pretty mechanical.
