Chris Tate 23d95a99fd Name program modules by the entry's file name so profiles match in every checkout ...

Each partition's source file name was the program entry's absolute path,
and profiles name a module's local functions after it. Since programs keep
partition-local functions internal (#2449), a profile collected in one
directory missed those functions in builds from any other: a native
compiler profile collected on main named 27% of its records, holding 2.2%
of its counts, after the checkout's path. Modules now carry the entry's
file name. The partition cache key still includes the full path.
