[tarantool-patches] Re: [PATCH v2] travis-ci: fix LTO and clang

[Alexander Turenko <alexander.turenko@tarantool.org>]

Pushed to master, 2.1 and 1.10.

1.10 has no LTO targets, but I saved CMAKE_EXTRA_PARAMS to keep
CI related files as similar as possible and because we possibly will
need it for GitLab CI targets.

I fixed minor points here and there, see below.

WBR, Alexander Turenko.

were postponed? Fixed.

We use tab symbol for indentation in C sources. Fixed.

Added a whitespace to indent '(long) curl_verbose' on the same column
with 'req->curl_request.easy'.
