Alex Lorenz 11e1f2366f [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.
