We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Summary:
That allows to get the same data as produced by "llvm-cov report",
but in JSON format, which is better for further processing by end users.

Region coverage is difficult to explain without going deep into how
coverage is implemented. Instantiation coverage is easier to explain,
but probably not useful in most cases (templates don't exist in C, and
most C++ code contains relatively few templates).
This patch adds the options "-show-region-summary" and
"-show-instantiation-summary" to allow hiding those columns.
"-show-instantiation-summary" is turned off by default.

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

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.

The llvm-cov version information will be useful to the user when comparing the code coverage across different versions of llvm-cov. This patch provides the llvm-cov version information in the generated coverage report.

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".

When using orbis-llvm-cov.exe to generate the HTML report, the HTML report
can look quite different to the source file if it includes tabs.The default
tab size is 2 spaces instead of 8 spaces. A command line switch is
be added to set the tab size.

Add an option to specify a symbol demangler (as well as options to the
demangler). This can be used to make reports more human-readable.
This option is especially useful in -output-dir mode, since it isn't as
easy to manually pipe reports into a demangler in this mode.

This makes it a bit more generic, in case we want to emit summary
reports in different formats in the future.

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.

- Avoid accidentally closing stdout twice.

This commit expands llvm-cov's functionality by adding support for a new code coverage
tool that uses LLVM's coverage mapping format and clang's instrumentation based profiling.
The gcov compatible tool can be invoked by supplying the 'gcov' command as the first argument,
or by modifying the tool's name to end with 'gcov'.
