How is this hunk (including assert.h) connected with "Replace boost::function with std::function (C++11)"?

@paveljanik That is a very good question! Surprisingly it seems like #include <boost/function.hpp> give you assert and limits too.
Compiling without #include <assert.h> in src/bench/bench.cpp:
CXX bench/bench_bench_bitcoin-bench.o
bench/bench.cpp: In member function ‘bool benchmark::State::KeepRunning()’:
bench/bench.cpp:95:86: error: ‘assert’ was not declared in this scope
assert(count != 0 && "count == 0 => (now == 0 && beginTime == 0) => return above");
Compiling without #include <limits> in src/bench/bench.h:
CXX bench/bench_bench_bitcoin-bench_bitcoin.o
In file included from bench/bench_bitcoin.cpp:5:0:
bench/bench.h: In constructor ‘benchmark::State::State(std::__cxx11::string, double)’:
bench/bench.h:52:23: error: ‘numeric_limits’ is not a member of ‘std’
minTime = std::numeric_limits<double>::max();

Perfect answer, thanks! I should have tested it myself 8)

Micro-benchmarking framework part 1 Cherry-picked from the following upstream PRs: - bitcoin/bitcoin#6733 - bitcoin/bitcoin#6770 - bitcoin/bitcoin#6892 - Excluding changes to `src/policy/policy.h` which we don't have yet. - bitcoin/bitcoin#7934 - Just the benchmark, not the performance improvements. - bitcoin/bitcoin#8039 - bitcoin/bitcoin#8107 - bitcoin/bitcoin#8115 - bitcoin/bitcoin#8914 - Required resolving several merge conflicts in code that had been refactored upstream. The changes were simple enough that I decided it was okay to impose merge conflicts on pulling in those refactors later. - bitcoin/bitcoin#9200 - bitcoin/bitcoin#9202 - Adds support for measuring CPU cycles, which is later removed in an upstream PR after the refactor. I am including it to reduce future merge conflicts. - bitcoin/bitcoin#9281 - Only changes to `src/bench/bench.cpp` - bitcoin/bitcoin#9498 - bitcoin/bitcoin#9712 - bitcoin/bitcoin#9547 - bitcoin/bitcoin#9505 - Just the benchmark, not the performance improvements. - bitcoin/bitcoin#9792 - Just the benchmark, not the performance improvements. - bitcoin/bitcoin#10272 - bitcoin/bitcoin#10395 - Only changes to `src/bench/` - bitcoin/bitcoin#10735 - Only changes to `src/bench/base58.cpp` - bitcoin/bitcoin#10963 - bitcoin/bitcoin#11303 - Only the benchmark backend change. - bitcoin/bitcoin#11562 - bitcoin/bitcoin#11646 - bitcoin/bitcoin#11654 This pulls in all changes to the micro-benchmark framework prior to December 2017, when it was rewritten. The rewrite depends on other upstream PRs we have not pulled in yet. This does not pull in all benchmarks prior to December 2017. It leaves out benchmarks that either test code we do not have yet (except for the `FastRandomContext` refactor, which I decided to pull in), or would require rewrites to work with our changes to the codebase.
