In addition to tracking input and output ranges in the IC-stubs with a Smi fastpath (SmiAdd and SmiSub, currently) this CL also introduces two IC stubs that have no fast-path by still track ranges and update the range feedback. We are able to distinguish between the following ranges (encoding of the lattice is shown in the parens): - u-smi (0000) - smi (0001) - uint31 (0010) - int32 (0011) - uint32 (0100) - int64 (1xxx) and (x1x1) BUG= R=fschneider@google.com, srdjan@google.com, zra@google.com Review URL: https://codereview.chromium.org//735543003 git-svn-id: https://dart.googlecode.com/svn/branches/bleeding_edge/dart@42370 260f80e4-7a28-3924-810f-c04153c831b5
