coverage: Rename `mir::coverage::BranchInfo` to `CoverageInfoHi` This opens the door to collecting and storing coverage information that is unrelated to branch coverage or MC/DC, during MIR building. There is no change to the output of coverage instrumentation, but one deliberate change is that functions now *always* have an attached `CoverageInfoHi` (if coverage is enabled and they are eligible), even if they didn't collect any interesting branch information. --- `@rustbot` label +A-code-coverage
