Hi,
These patches are a mix of features, bugfixes, and quality of life
improvements.
* fixes a wrong line count when multiple blocks touch the same line
* -fpath-coverage and -fcondition-coverage implies -ftest-coverage
(.gcno, a prerequisite for running gcov)
* gcov-dump prints paths and the correct offset of the conditions tag.
I noticed a regression in the gcov test suite which I bisected to this
commit. The breakage is from discriminators being added to the
locations, which caused unintended misses in a hash set in profile.cc.

Rewrite assign_discriminators
The prime paths test change is quite harmless, and the occasional
update to tests like this should be expected. The pr-* tests do catch
the real problem.
Bootstrapped and regtested on x86_64-linux-gnu
Jørgen Kvalsvik (5):
gcov: Only consider pure locations in line mapping
Update expected number of prime paths in test case
gcov-dump: Print start-position for conditions
gcc: -f*-coverage implies -ftest-coverage
gcov-dump: Print PATHS tag
