--experimental_split_coverage_postprocessing now works in combination with --experimental_generate_llvm_lcov, which required adding the runtime objects as inputs to the separate coverage post-processing spawn. Previously, they were only added to the runfiles of the test action, which aren't (and shouldn't) be added to the coverage spawn.

As a side effect, this provides a more natural fix for #15121 than bb6f1a7, which added an additional check to only add those runtime objects to the llvm-cov command line that were present in runfiles. Now, since all runtime objects are staged as inputs, they are known to be available. This improves coverage accuracy when e.g. runtime objects are packaged into jars and loaded at runtime.

Along the way the common setup for LLVM-based coverage tests has been extracted into a helper function and the tests have been updated to work with a broader range of clang versions. Previously, tests weren't run at all due to the clang version on the runners not falling into the restrictive range. Now, the tests are executed on the Ubuntu 20.04 runner (but not on any other runners, including macOS).

Closes #18634.

`--experimental_split_coverage_postprocessing` now works in combination with `--experimental_generate_llvm_lcov`, which required adding the runtime objects as inputs to the separate coverage post-processing spawn. Previously, they were only added to the runfiles of the test action, which aren't (and shouldn't) be added to the coverage spawn.

As a side effect, this provides a more natural fix for bazelbuild#15121 than bb6f1a7, which added an additional check to only add those runtime objects to the `llvm-cov` command line that were present in runfiles.

Release Notes:

+ Automatic code cleanup. (#18417)
+ Update CODEOWNERS for 6.3.0 (#18369)
+ Overrides specified by non-root modules no longer cause an error, and are silently ignored instead. They were originally treated as an error to allow for the future possibility of overrides in the transitive dependency graph working together; but we've deemed that infeasible (and even if it was, it'd be so complicated and confusing to users that it would not be a good addition). (#18388)
+ Add implementation deps support for Objective-C (#18372)
+ Update release notes scripts (#18400)
+ Prevent CredentialHelperEnvironment crash when invoking Bazel outside of a workspace. (#18430)
+ Use wall-time for credential helper invalidation (#18413)
+ blaze_util_posix: handle killpg failures (#18403)
+ Pass version to java_runtimes created by local_java_repository (#18415)
+ Add jsonproto option to query --output flag (#18438)
+ Don't eagerly flatten a `NestedSet` in `RepoMappingManifestAction` (#18419)
+ rules_go & rules_python are failing in Downstream CI with Bazel@HEAD (#18447)
+ Move credential helper setup into remote_helpers.sh so it can be reused by other shell tests. (#18453)
+ Wire credential helper to repository fetching. (#18429)
+ Updates/fixes to relnotes script (#18470)
+ Report percentual download progress in repository rules (#18471)
+ Support remote symlink outputs when building without the bytes. (#18476)

+ Fix relnotes script (#18491)
+ Fix Xcode 14.3 compatibility (#18490)
+ Fix #18493. (#18514)
+ Extend the credential helper default timeout to 10s. (#18527)
+ Fix formatting of release notes (#18534)
+ Use extension rather than local names in ModuleExtensionMetadata (#18536)
+ [credentialhelper] Ignore all errors when writing stdin (#18540)
+ Improve error on invalid `-//foo` and `-@repo//foo` options (#18516)
+ Implement failure circuit breaker (#18541)
+ Actually check `TEST_SHARD_STATUS_FILE` has been touched (#18418)
+ Ignore hash string casing (#18414)
+ Error if repository name isn't supplied (#18425)
+ Track repo rule label attributes after the first non-existent one (#18412)
+ Add ServerCapabilities into RemoteExecutionClient (#18442)

+ Fix error when script is run after the final tag is created. (#18638)
+ Fix WORKSPACE toolchain resolution with `--enable_bzlmod` (#18649)
+ Add `ActionExecutionMetadata` as a parameter to `ActionInputPrefetcher#prefetchFiles`. (#18656)
+ Use failure_rate instead of failure count for circuit breaker  (#18559)
+ Update ignored_error logic for circuit_breaker (#18662)
+ Don't rewind the build if invocation id stays the same (#18670)
+ Fix potential memory leak in UI (#18659)
+ Test that a credential helper can supply credentials for bzlmod. (#18663)
+ Add flag --experimental_collect_code_coverage_for_generated_files. (#18664)
+ Options specified on the pseudo-command `common` in `.rc` files are now ignored by commands that do not support them as long as they are valid options for *any* Bazel command.

+ Revert "Don't eagerly flatten a `NestedSet` in `RepoMappingManifestAction` (#18419)" (#18886)
+ Additional source inputs can now be specified for compilation in cc_library targets using the additional_compiler_inputs attribute, and these inputs can be used in the $(location) function. Fixes #18766. (#18882)
