Sam McCall 573050e703 [include-fixer] Remove line number from Symbol identity
Summary:
Remove line number from Symbol identity.

For our purposes (include-fixer and clangd autocomplete), function overloads
within the same header should mostly be treated as a single combined symbol.

We may want to track individual occurrences (line number, full type info)
and aggregate this during mapreduce, but that's not done here.

Sam McCall b27dc2245f [include-fixer] Add usage count to find-all-symbols.
Summary:
Add usage count to find-all-symbols.

FindAllSymbols now finds (most!) main-file usages of the discovered symbols.
The per-TU map output has NumUses=0 or 1 (only one use per file is counted).
The reducer aggregates these to find the number of files that use a symbol.

The NumOccurrences is now set to 1 in the mapper rather than being inferred by
the reducer, for consistency.

The idea here is to use NumUses for ranking: intuitively number of files that
use a symbol is more meaningful than number of files that include the header.

Benjamin Kramer bdb2171c15 [include-fixer] Load symbol index asynchronously.
We don't actually need the index until parse time, so fetch it in the
background and start parsing. By the time it is actually needed it's
likely that the loading phase has completed in the background.

Haojian Wu c99f72868d [include-fixer] Support processing multiple files in one run.
Summary:
Previously, if we pass multiple files or a file pattern (e.g. /path/to/*.cc) to
include-fixer, include-fixer will apply all replacements to the first argument,
which probably causes crashes.

With this patch, include-fixer can process multiple files now.

Vim and Emacs integration are tested manually.

Haojian Wu adedac68dc [include-fixer] Correct nested class search for identifiers with scoped information
Summary:
include-fixer will firstly try to use scoped namespace context information to
search identifier. However, in some cases, it's unsafe to do nested class
search, because it might treat the identifier as a nested class of scoped
namespace.

Given the following code, and the symbol database only has two classes: "foo" and
"b::Bar".

    namespace foo { Bar t; }

Before getting fixing, include-fixer will never search "Bar" symbol.
Because it firstly tries to search "foo::Bar", there is no "Bar" in foo namespace,
then it finds "foo" in database finally. So it treats "Bar" is a nested class
of "foo".

Summary:
This is an initial version of fixing namespace issues by adding missing
namespace qualifiers to an unidentified symbol.

This version only fixes the first discovered unidentified symbol.
In the long run, include-fixer should fix all unidentified symbols
with a same name at one run.

Currently, it works on command-line tool. The vim integration is not
implemented yet.

Summary:
we should only deduplicate symbols after matching symbols with the
undefined identifier. This patch tries to fix the situation where matching
symbols are deleted when it has the same header as a non-matching symbol, which
can prevent finding the correct header even if there is a matched symbol.

Benjamin Kramer 5e6b35f4d1 [include-fixer] Also look up prefixes of queries.
This is used to find nested classes. For a nested name foo::bar::qux we
will first look up foo::bar::qux, then foo::bar, then foo unless we find
a result. This is used to support nested classes which are not part of
the index but can only be used if the header for the parent context is
included.

Benjamin Kramer ad93500c52 [include-fixer] Work around partial names in both directions.
We already handled the case where we had a nested name specifier where
parts from the beginning don't get a callback, also handle the case
where the end doesn't get a callback. This happens with function calls
in unknown namespaces.

The way we do this for now based on character data is a bit of a hack, we
may need to refine this later or fix clang to produce different callbacks.

Benjamin Kramer 6b23626192 [include-fixer] Add a prototype for a new include fixing tool.
Summary:
The goal of this tool is fairly simple, look up unknown identifiers in a
global database and add the corresponding #include line. It accomplishes
this by hooking into Sema as an ExternalSemaSource and responding to typo
correction callbacks. This means we can see the unknown identifier before
it's being munged by error recovery.

This doesn't work perfectly yet as some typo corrections don't emit
callbacks (delayed typos), but I think this is fixable. We also handle
only one include at a time as this is meant to be run directly from
the editing environment eventually. Adding multiple includes at the same
time is tricky because of error recovery.

This version only has a a dummy database, so all you can do is fixing
missing includes of <string>, but the indexer to build a database will
follow soon.
