Vedant Kumar 933b37f99f [llvm-cov] Unify region marker placement between text/html modes
Make sure that the text and html emitters always emit the same set of
region markers, and avoid emitting redundant markers for line segments
which don't end on the line they start on.

This is related to D35925, and depends on D36014

Eli Friedman c0c182cce1 [llvm-cov] Rearrange entries in report index.
Files which don't contain any functions are likely useless; don't
include them in the main table. Put the links at the bottom of the
page, in case someone wants to figure out coverage for code inside
a macro.

Not sure if this is the best solution, but it seems like an
improvement.

Alex Lorenz 35369c1eb6 [llvm-cov] Avoid 0% when reporting something that's 0/0
This commit makes llvm-cov avoid showing 0% (0/0) coverage for things
like file function coverage, etc. in reports and HTML output. This can happen
for files like headers that have macros but no functions. This commit makes
llvm-cov report - (0/0) instead.

Vedant Kumar 5c61c70387 [llvm-cov] Do not print out the filename of the object file
When we load coverage data from multiple objects, we don't have a way to
attribute a source object to a function record. Printing out the object
filename next to the source filename is already not very useful: soon,
it'll actually become misleading. Stop printing out the filename now.

Vedant Kumar bc6479850e [llvm-cov] Get rid of all invalid filename references
We used to append filenames into a vector of std::string, and then
append a reference to each string into a separate vector. This made it
easier to work with the getUniqueSourceFiles API. But it's buggy.

std::string has a small-string optimization, so you can't expect to
capture a reference to one if you're copying it into a growing vector.
Add a test that triggers this invalid reference to std::string scenario,
and kill the issue with fire by just using ArrayRef<std::string>
everywhere.

Vedant Kumar 016111f7b9 [llvm-cov] Track function and instantiation coverage separately
These are distinct statistics which are useful to look at separately.

Example: say you have a template function "foo" with 5 instantiations
and only 3 of them are covered. Then this contributes (1/1) to the total
function coverage and (3/5) to the total instantiation coverage. I.e,
the old "Function Coverage" column has been renamed to "Instantiation
Coverage", and the new "Function Coverage" aggregates information from
the various instantiations of a function.

One benefit of making this switch is that the Line and Region coverage
columns will start making sense. Let's continue the example and assume
that the 5 instantiations of "foo" cover {2, 4, 6, 8, 10} out of 10
lines respectively. The new line coverage for "foo" is (10/10), not
(30/50).  The old scenario got confusing because we'd report that there
were more lines in a file than what was actually possible.

These asserts are making tests fragile. The renderer does not enter an

Vedant Kumar 0b33f2c003 [llvm-cov] Fix issues with segment highlighting in the html view
The text and html coverage views take different approaches to emitting
highlighted regions. That's because this problem is easier in the text
view: there's no need to worry about escaping text or adding tooltip
content to a highlighted snippet.

Unfortunately, the html view didn't get region highlighting quite right.

This patch fixes the situation, bringing parity between the two views.
