Yijie Ma	bd940c0dd5	[Fuzzing] Add a build config option which enables Clang source-based code coverage (#32858 ) This maybe used to quickly verify the code coverage of a modified test locally (e.g. fuzzer). Example: ``` # Build and run target; the raw profile will be written to $LLVM_PROFILE_FILE when the program exits $ bazel build --config=dbg --config=fuzzer_asan --config=coverage //test/core/end2end/fuzzers:api_fuzzer $ LLVM_PROFILE_FILE="api_fuzzer.profraw" bazel-bin/test/core/end2end/fuzzers/api_fuzzer test/core/end2end/fuzzers/api_fuzzer_corpus/* # Create coverage report $ llvm-profdata-14 merge -sparse api_fuzzer.profraw -o api_fuzzer.profdata $ llvm-cov-14 report ./bazel-bin/test/core/end2end/fuzzers/api_fuzzer --instr-profile=api_fuzzer.profdata ``` Sample report: `f94e444f25/gistfile1.txt` One trick is that the binary needs to be statically linked, e.g. specify `linkstatic = 1` on the BUILD target.

[Fuzzing] Add a build config option which enables Clang source-based code coverage (#32858 )

This maybe used to quickly verify the code coverage of a modified test
locally (e.g. fuzzer).

Example:
```
# Build and run target; the raw profile will be written to $LLVM_PROFILE_FILE when the program exits
$ bazel build --config=dbg --config=fuzzer_asan --config=coverage //test/core/end2end/fuzzers:api_fuzzer
$ LLVM_PROFILE_FILE="api_fuzzer.profraw" bazel-bin/test/core/end2end/fuzzers/api_fuzzer test/core/end2end/fuzzers/api_fuzzer_corpus/*

# Create coverage report
$ llvm-profdata-14 merge -sparse api_fuzzer.profraw -o api_fuzzer.profdata
$ llvm-cov-14 report ./bazel-bin/test/core/end2end/fuzzers/api_fuzzer --instr-profile=api_fuzzer.profdata
```

Sample report:
f94e444f25/gistfile1.txt

One trick is that the binary needs to be statically linked, e.g. specify
`linkstatic = 1` on the BUILD target.
See https://clang.llvm.org/docs/SourceBasedCodeCoverage.html for more
info.
