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.

llvm-cov writes out an index file in '-output-dir' mode, albeit not a
very informative one. Try to fix that by using the CoverageReport API to
include some basic summary information in the index file.

In r279628, we made SourceCoverageView list the binary associated with a
view and started adding labels (e.g "Source: foo" or "Function: bar") to
everything. Condense this information a bit to unclutter reports.

This patch provides easy navigation to find the zero count lines, especially useful when the source file is very large.

This patch includes the following changes:
- Included header "Code coverage report" and include the date that the report was created.
- Included title (as specified in a command line option, (i.e llvm-cov -project-title="Simple Test")
- In the summary, list the elf files that the source code file has contributed to.
- Used column heading for "Line No.", "Count No.", Source".

- Add renderView{Header,Footer}, renderLineSuffix, and hasSubViews to
support creating tables with nested views.
- Move the 'Format' cl::opt to make it easier to extend.
- Just create one function view file, instead of overwriting the same
file for every new function. Add a regression test for this.

This index lists the reports available in the 'coverage' sub-directory.
This will help navigate coverage output from large projects.
This commit factors the file creation code out of SourceCoverageView and
into CoveragePrinter.

Passing -output-dir path/to/dir to llvm-cov show creates path/to/dir if
it doesn't already exist, and prints reports into that directory.
In function view mode, all views are written into
path/to/dir/functions.$EXTENSION. In file view mode, all views are
written into path/to/dir/coverage/$PATH.$EXTENSION.
Changes since the initial commit:
- Avoid accidentally closing stdout twice.

This reverts commit r273971. test/profile/instrprof-visibility.cpp is
failing because of an uncaught error in SafelyCloseFileDescriptor.

Passing -output-dir path/to/dir to llvm-cov show creates path/to/dir if
it doesn't already exist, and prints reports into that directory.
In function view mode, all views are written into
path/to/dir/functions.$EXTENSION. In file view mode, all views are
written into path/to/dir/coverage/$PATH.$EXTENSION.

If a sub-view has already been rendered, it's helpful to re-render the
expansion site before rendering the next expansion view. Make this fact
explicit in the rendering interface, instead of hiding it behind an
awkward Optional<LineRef> parameter.
llvm-svn: 273789
This makes it easier to add renderers for new kinds of output formats.
- Define and document a pure-virtual coverage rendering interface.
- Move the text-based rendering logic into its a new file.
- Re-work the API to better reflect the presentation/formatting split.
