Programs built by the Finch compiler free their memory

Browse source

gen.fch never dropped anything (it was the bootstrap compiler); now it does what the C++ one did: owned variables are
dropped when their scope ends (defers interleaved, newest first), return moves a local out, assignments drop the old
value, temporaries nobody keeps are released, values an expression holds are dropped when try/or leave early,
clear/resize/remove/map.clear drop what goes, free() drops the pointee. The compiler itself now frees as it goes.

MEMCHECK=1 tests/run.sh: 108 passed under valgrind with --leak-check=full.
