[llvm-cov] Add SourceNames to SourceCoverageViews, NFC

A SourceName can be a file or a function. It makes sense to attach this
information to a SourceCoverageView, seeing as views (1) already point
to the text corresponding to the relevant source code and (2) are
already used to render that text along with the SourceNames.

This is a nice cleanup which is independent of the upcoming html patch.

While we're at it, document the fields in SourceCoverageView.

[llvm-cov] Rename SourceCoverageView::LineCoverageInfo to LineCoverageStats, NFC

This cuts down on the amount of code we have to move into a `protected`
section of SourceCoverageView for the upcoming html patch. It also makes
the code a bit clearer: having two LineCoverageInfo's is strange.

InstrProf: Teach llvm-cov to show the max count instead of the last

When multiple regions start on the same line, llvm-cov was just
showing the count of the last one as the line count. This can be
confusing and misleading for things like one-liner loops, where the
count at the end isn't very interesting, or even "if" statements with
an opening brace at the end of the line.

Instead, use the maximum of all of the region start counts.

llvm-cov: Disentangle the coverage data logic from the display (NFC)

This splits the logic for actually looking up coverage information
from the logic that displays it. These were tangled rather thoroughly
so this change is a bit large, but it mostly consists of moving things
around. The coverage lookup logic itself now lives in the library,
rather than being spread between the library and the tool.

llvm-cov: Rework the API for getting the coverage of a file (NFC)

This encapsulates how we handle the coverage regions of a file or
function. In the old model, the user had to deal with nested regions,
so they needed to maintain their own auxiliary data structures to get
any useful information out of this. The new API provides a sequence of
non-overlapping coverage segments, which makes it possible to render
coverage information in a single pass and avoids a fair amount of
extra work.
