compiler.tree.modular-arithmetic: Don't require that fixnum+ works on tuple slots marked fixnum. This is probably a speed regression. XXX revisit

compiler.tree.identities: the identity on mod was useless too, because we already have a rewrite rule which handles this case in compiler.tree.propagation

compiler.tree.modular-arithmetic: eliminate >bignum calls where possible, convert fixnum-shift to fixnum-shift-fast if shift count is positive, don't run if there are no modular values

compiler.tree.propagation: be more careful with intervals, ensuring that the inferred interval of a value is a subset of the value class's interval. This improves accuracy, for example [ >fixnum 1 + >fixnum most-positive-fixnum <= ] constant-folds to true

Overflowing fixnum intrinsics now expand into several CFG nodes. This speeds up the common case since only the uncommon case is now a stack syncpoint
