d4804e070f Do not reserve extra threads after max threads optimization for simple queries 
Before this patch pipeline.setMaxThreads() was called with 0 (since
streams.size() == 0, while pipes.size() == 1), which leads that
pipeline.getMaxThreads() returns max_streams.

While this threads were not used, they were reserved, which should not
happens either.

f4d9002182 Rename "Non-significant" to "Not for changelog". 
The previous name was not universally liked, because technically a PR
might be very much significant, we just don't want to mention it in the
changelog.

322d731d28 Remove extra copying from addressToLine 
The line is already serialized to the same arena, so there is no need to
copy it. Also add this function to query profiler test, so that it has
some coverage.

087d8ab020 A follow-up for trace log overflow in perftests 
The start was in https://github.com/ClickHouse/ClickHouse/pull/11026
It turned out that the problem was due to the incorrect mutate()
implementation that lead to quadratic amount of column copying. This
problem has since been fixed.

Remove the excessively verbose logging, and also change appendToBlock of
LogElement's to accept mutable columns instead of accepting a block and
mutating it on each call. It looks wasteful, even though it is almost a
noop.

23044ac02c Disable -Wsequence-point on gcc10 (otherwise it stuck on GatherUtils compiling) 
clang (10.0.0 is fine BTW) will warn about this anyway on CI.

For the debug build gcc10:

- before patch:
  - concat.cpp -> >5m (stuck on cc1plus, not as)
  - has.cpp    -> >10m (stuck on cc1plus, not as)

- after this patch:
  - concat.cpp -> 1m16s
  - has.cpp    -> 4m (and most of the time eats, as from binutils 2.34.50.20200508)

Command for build:
- ninja src/Functions/GatherUtils/CMakeFiles/clickhouse_functions_gatherutils.dir/concat.cpp.o
- ninja src/Functions/GatherUtils/CMakeFiles/clickhouse_functions_gatherutils.dir/has.cpp.o

The test case should be reduced and then it can be reported to the gcc
bugzilla.

P.S. Looks like a signal not to switch to gcc10 for now
