Description

The function merge-code-coverage-data and destructive-merge-code-coverage-data merge two code-coverage-data objects.

Merging means taking all the files from ccd1 together with those files from ccd2 which do not have information in ccd1. For files that appear in both ccd1 and ccd2, the information in ccd2 is ignored.

merge-code-coverage-data creates a new code-coverage-data object containing the information for each file, and with name name.

destructive-merge-code-coverage-data adds to ccd1 those files from ccd2 which are not already there, and returns ccd1.

If either of the datas is the internal code-coverage-data object, the file information is copied, so it does not change anymore. Otherwise it just copies the pointer, because the file information is read-only.
