Back in https://reviews.llvm.org/D124490 we added a block coverage mode that instruments a subset of basic blocks using single byte counters to get coverage for the whole function. This commit adds a test to make sure that we correctly assign branch weights based on the coverage profile. I noticed this test was missing after seeing that we had no coverage on `PGOUseFunc::populateCoverage()` https://lab.llvm.org/coverage/coverage-reports/coverage/Users/buildslave/jenkins/workspace/coverage/llvm-project/llvm/lib/Transforms/Instrumentation/PGOInstrumentation.cpp.html#L1383
