Allow specifying number of iterations via --benchmark_min_time. (#1525)
* Allow specifying number of iterations via --benchmark_min_time.

Make the flag accept two new suffixes:
 + <integer>x: number of iterations
 + <floag>s: minimum number of seconds.

This matches the internal benchmark API.

* forgot to change flag type to string

* used tagged union instead of std::variant, which is not available pre C++14

* update decl in benchmark_runner.h too

* fixed errors

* refactor

* backward compat

* typo

* use IterationCount type

* fixed test

* const_cast

* ret type

* remove extra _

* debug

* fixed bug from reporting that caused the new configs not to be included in the final report

* addressed review comments

* restore unnecessary changes in test/BUILD

* fix float comparisons warnings from Release builds

* clang format

* fix visibility warning

* remove misc file

* removed  backup files

* addressed review comments

* fix shorten in warning

* use suffix for existing min_time specs to silent warnings in tests

* fix leaks

* use default min-time value in flag decl for consistency

* removed double kMinTimeDecl from benchmark.h

* dont need to preserve errno

* add death tests

* Add BENCHMARK_EXPORT to hopefully fix missing def errors

* only enable death tests in debug mode because bm_check is no-op in release mode

* guard death tests with additional support-check macros

* Add additional guard to prevent running in Release mode
