a0a3401ef1 Don't special-case br_table with an empty table. 
Empty br_table tables are very uncommon (they're easy for wasm producers to
optimize away), so we don't need to special-case them.

0deaa616a3 Record identity assignments in regalloc constraint solver. 
Fixes #147.

The Solver::reassign_in() method would previously not record fixed
register assignments for values that are already in the correct
register. The register would simply be marked as unavailable for the
solver.

This did have the effect of tripping up the sanity checks in
Solver::add_var() when that method was called with such a "reassigned"
value. The function can be called for a value that already has a fixed
assignment, but the sanity checks want to make sure the variable
constraints are compatible with the existing fixed assignment. When no
such assignment could be found, the method panicked.

To fix this, make sure that even identity reassignments are recorded
in the assignments vector. Instead, filter the identity assignments out
before scheduling a move sequence for the assignments.

Also add some debug tracing to the regalloc solver.

4afa5df3b6 Remove the last_inst_return field. 
It's not necessary to explicitly track whether the last instruction is a
return; if the builder for the last block isn't filled by the time we reach
the end, it needs a return to fill it.

ea1d053831 Simplify the "am I in unreachable code" predicate. 
The phantom unreachable stack is only used when the real unreachable stack is
active, so it's sufficient to check whether the real unreachable stack is empty.
