It fixes the following error on Fedora-rawhide:
 error: Failed dependencies:
	pmdk-debuginfo(x86-64) = 1.7-1.fc32 is needed by libpmem-debug-debuginfo-1.7-1.fc32.x86_64

TRAVIS_COMMIT_RANGE is usually invalid for force pushes.
Fix it when used with a non-upstream repository
by setting to the following value: $LAST_MERGE_COMMIT..HEAD

The commit fix the issue with concurrent_hash_map_rehash_0_helgrind test

header_features was only declared (not defined) in concurrent_hash_map header.
This means that (until C++17) it can be used only in places where address of
this constant is not needed. In operator != we access one member of header_fatures
which requrires it to be declared. This only fails for some compilers like clang-9
because rest of the evaluate this expression at compile time (this is a compiler
decision whether to do this at compile time or runtime).

Fix this issue by creating function header_features().
