Subject: xdiff: drop CMP_ENV macro from xhistogram

This macro has been unused since 43ca7530df (xdiff/xhistogram: rely on
xdl_trim_ends(), 2011-08-01). The function that called it went away
there, and its use in the CMP() macro was inlined. It probably should
have been deleted then, but nobody noticed.
