configure: Add switch for clang's "source-based" code coverage feature
This adds instrumentation to the binaries. At the end of their
execution, these will then write a file containing information which code
was executed. This can be used for code coverage analysis.
[ChangeLog][QtCore][configure] Add switch "-coverage source-based" to
enable clang's "source-based" code coverage feature. This can be used
for code coverage analysis.
