Googler 34ca16f4aa Partially fix MacOS llvm coverage collection
This allows setting GCOV on the command line to overwrite the default setting, which points to /usr/bin/gcov. In order to use this, you also need to disable the gcov coverage feature and enable the llvm coverage feature instead. The full command-line looks like this:

GCOV=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/llvm-profdata bazel coverage --features=llvm_coverage_map_format --features=-gcc_coverage_map_format //cpp:test

Progress on #10457.

Googler d545fa4f79 C++: Move default linker flags with libs after libraries
Default linker flags contains flags like -lstdc++ which should come after the
user libraries. The library flags are removed from default linker flags and added to link_libs instead which comes after user libraries.

See #9254

Incompatible flag bug: https://github.com/bazelbuild/bazel/issues/10905

I introduce a new method to repositories ctx that allows checking the value of a Starlark semantic option from a repository rule.

Googler 4de26b53a6 Remove need for exported_by or linked_statically_by
For now we will restrict allowed exports to the same package. At the same time
static_deps should be used to take into account what should be linked into a
shared library.

Googler cfe68f6bc7 Fix immutable frozen set bug in defs.bzl
When adding tags to a native cc_library rule that is created through a macro we
were not properly considering the case where the tags came from a different
file and therefore were frozen. This caused an error.

Googler 6cfb2fba70 Fix codebase in preparation for incompatible_use_cc_configure_from_rules_cc
We're working on removing C++ toolchain autoconfiguration logic out of Bazel,
and moving towards using rules_cc repository for it. Some bzl files will no
longer be available through bazel/tools/cpp/*, but through
@rules_cc/cc/*.

Googler 262ebec3c2 Fix buildifier warnings in @rules_cc
Fixes:

* Enabled buildifier on the Bazel CI again
* Added Skydocs where missing
* Moved public files out of .../private/... (e.g. cc_toolchain_config_lib.bzl)
* Reformatted
* Removed unused loads
* Using relative labels for cc_configure related files
* Added development dependency on rules_proto
    * they're not in the federation yet, so hand rolling in rules_cc's WORKSPACE file
* Added development dependency on rules_python (from federation)
* Cleaned up copybara (notable change - not using @rules_cc in labels inside rules_cc repo)
* Made cc_flags_supplier usable internally
* Moved load statements to the top of the bzl file
* Moved runfiles to the tools directory
* Unified toolchain_utils.bzl and find_cc_toolchain.bzl

fweikert 29da92c66c Use rules_pkg for building releases
This commit allows the creation of distributions, with 0.0.1 being the first version.
See distro/README.md for details on how to build a release.

This commit also uses a new version of the Bazel federation that contains rules_pkg 0.2.2 instead of 0.2.1.

There are still some problems with the WORKSPACE stanza that is being printed by the release notes generation script, though:
- It references a //cc:deps.bzl file, which doesn't exist. I have to modify the scripts in rules_pkg to support a flag like 'has_deps'.
- It doesn't support the Bazel federation yet, since it always tells users to download code from the rules_cc repository.

Googler 42ed56d8ac Remove unused load statements from .bzl files
BEGIN_PUBLIC
Remove unused load statements from .bzl files

After transitive loads have been disabled in Blaze, unused load statements have
no effect (besides not useful memory consumption).

The CL has been created automatically by calling `buildifier --lint=fix --warnings=load` on all .bzl files.

The following additional command were run on all affected files to clean them up:

  * buildifier -a -v --lint=fix --warnings=load-on-top
    Moves all load statements to the top of a file
  * buildifier -a -v --lint=fix --warnings=same-origin-load
    Compresses all load statements from the same .bzl file to one load statement

Marcel Hlopko d991801638 Add find_cc_toolchain.bzl to help accessing current C++ toolchain
This is to help migrating for:

* https://github.com/bazelbuild/bazel/issues/7260
* https://github.com/bazelbuild/bazel/issues/7643

It's mostly a copy of the file in
`@bazel_tools//tools/cpp:toolchain_utils.bzl`, with a small difference -
it depends on `@rules_cc//cc:toolchain_type`, not on
`@bazel_tools//tools/cpp:toolchain_type`.

Marcel Hlopko e283f126b5 Add //cc:toolchain_type alias to allow forward migration with Bazel 0.27
This target will eventually be the canonical place for C++ toolchain
type. Currently the actual target resides in @bazel_tools, but that will
soon change.
