ccls/src/include_complete.hh
Fangrui Song c085e07b19 Extend .ccls
* Add %h for C header files (the suffix .h is considered a C header, not a C++ header)
* Add %hpp for C++ header files
* If .ccls exists, it provides full command line for files not specified by compile_commands.json (before, compile_commands.json was ignored)
* If the first line of .ccls is %compile_commands.json, it appends flags to compile_commands.json "arguments", instead of overriding.
  Files not specified by compile_commands.json will not be added to folder.entries, but their command line can be inferred from other files.

Also fix `#include <` completion of -I flags for clang < 8
