Various algorithmic improvements that reduce compile times (thanks Alexandre Pilkiewicz):
- Lattice: preserve sharing in "combine" operation
- Kildall: use splay heaps (lib/Heaps.v) for node sets
- RTLgen: add a "nop" before loops so that natural enumeration of nodes
coincides with (reverse) postorder
- Maps: add PTree.map1 operation, use it in RTL and LTL.
- Driver: increase minor heap size
