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. rdar://29246480 Differential Revision: https://reviews.llvm.org/D26615 llvm-svn: 287539
