CHECK_MESSAGE no longer works with DOCTEST_CONFIG_SUPER_FAST_ASSERTS

Description

While updating doctest, CHECK_MESSAGE broke and it causes a compilation failure. It looks like it was broke in c494843, it works in 2.1.0 while in 2.2.0 it fails with an error:

foo2.cpp:8:3: error: use of undeclared identifier 'DT_CHECK'
  CHECK_MESSAGE(x == 0, "Boo boo");
  ^
./doctest/doctest.h:2476:23: note: expanded from macro 'CHECK_MESSAGE'
#define CHECK_MESSAGE DOCTEST_CHECK_MESSAGE
                      ^
./doctest/doctest.h:2022:93: note: expanded from macro 'DOCTEST_CHECK_MESSAGE'
#define DOCTEST_CHECK_MESSAGE(cond, msg) do { DOCTEST_INFO(msg); DOCTEST_ASSERT_IMPLEMENT_2(DT_CHECK, cond); } while((void)0, 0)
                                                                                            ^
1 error generated.

I get the same error with 2.3.4.

Steps to reproduce

#define DOCTEST_CONFIG_IMPLEMENT_WITH_MAIN
#define DOCTEST_CONFIG_SUPER_FAST_ASSERTS
#include <doctest/doctest.h>

TEST_CASE("x")
{
  int x = 2;
  CHECK_MESSAGE(x == 0, "Boo boo");
}

Compile with clang++ without any special flags.

• doctest version: v2.3.4
• Operating System: Gentoo Linux amd64
• Compiler+version: clang 8.0.1 (both with libc++ and gcc's libstdc++)

Thanks for reporting this regression!

fixed in the dev branch - you can use it from there immediately. I'll release 2.3.5... at some point :)

I can confirm that my sample is now working with the dev branch 👍. I can't test it with my real code right now because of the two other bugs I've opened.
