Remove the expression combination counts from the default stats file, and add a new `--dump-ast-patterns` option, which will dump new `*_ast_patterns_*.txt` files. These contain the expression combinations in a similar S-expression format as Dfg already produces with `--dump-dfg-stats`. These dumps are not produced by just `--stats` as they are fairly expensive to compute. Currently the new option will dump at two points: just before we change to C types via widthMin usage, and just before emit.
