sommerfeld bcb141e5d0 Reuse the Hash_Entry `name' field to store the variable name when we
can (i.e., everything except environment variables, which aren't
stored in hash tables).

While we're here, inline the body of VarDelete into Var_Delete since
it's the only caller and it's just simpler that way when v->name can
share storage with the hash entry and may not need to be freed
separately.

Speeds up the infamous libc build benchhmark maybe 1% on PIII, 4% on
alpha pc164
