[PATCH] D30729: [ubsan] Skip range checks for width-limited values

[Vedant Kumar via Phabricator via cfe-commits]

- Fix an incorrect comment on the field "e2" in struct S. We emit a check for it because 0b11 = -1 = 3.
- Skip the range check on the field "e2" in struct S2, because the range of the bitfield is the same as the range clang infers for the enum.
