Automated rollback of commit a34fafd5f5e44a7a0992ef8c01415e766552ae90.
*** Reason for rollback ***
Rolling back. No time before 1.0.
*** Original change description ***
C++: Move tools/cpp from bazel_tools to rules_cc
Here we are duplicating bazel_tools/tools/cpp. The goal is for the BUILD files in bazel_tools/tools/cpp to have an alias that point to rules_cc. Then later on with the incompatible flag these aliases will no longer be valid.
Working towards #8743

-// Runfiles lookup library for Bazel-built C++ binaries and tests.
-//
-// USAGE:
-// 1. Depend on this runfiles library from your build rule:
-//
-// cc_binary(
-// name = "my_binary",
-// ...
-// deps = ["@rules_cc//cc/private/toolchain/runfiles"],
-// )
-//
-// 2. Include the runfiles library.
-//
-// #include "cc/private/toolchain/runfiles/runfiles.h"
-//
-// using bazel::tools::cpp::runfiles::Runfiles;
-//
-// 3. Create a Runfiles object and use rlocation to look up runfile paths:
-//
-// int main(int argc, char** argv) {
-// std::string error;
-// std::unique_ptr<Runfiles> runfiles(
-// Runfiles::Create(argv[0], &error));
-//
-// // Important:
-// // If this is a test, use Runfiles::CreateForTest(&error).
-// // Otherwise, if you don't have the value for argv[0] for whatever
-// // reason, then use Runfiles::Create(&error).
-//
-// if (runfiles == nullptr) {
-// ... // error handling
-// }
-// std::string path =
-// runfiles->Rlocation("my_workspace/path/to/my/data.txt");
-// ...
-//
-// The code above creates a Runfiles object and retrieves a runfile path.
-//
-// The Runfiles::Create function uses the runfiles manifest and the
-// runfiles directory from the RUNFILES_MANIFEST_FILE and RUNFILES_DIR
-// environment variables. If not present, the function looks for the
-// manifest and directory near argv[0], the path of the main program.
-//
-// To start child processes that also need runfiles, you need to set the right
-// environment variables for them:
-//
-// std::unique_ptr<Runfiles> runfiles(Runfiles::Create(argv[0], &error));
-//
-// std::string path = runfiles->Rlocation("path/to/binary"));
-// if (!path.empty()) {
-// ... // create "args" argument vector for execv
-// const auto envvars = runfiles->EnvVars();
-// pid_t child = fork();
-// if (child) {
-// int status;
-// waitpid(child, &status, 0);
-// } else {
-// for (const auto i : envvars) {
-// setenv(i.first.c_str(), i.second.c_str(), 1);
-// }
-// execv(args[0], args);
-// }
