[ubsan] Skip null check for "offsetof"-like computations When computing the address of a member expression, skip the null check on the base expression if it's a constant null pointer. This indicates that the null pointer is intentionally being manipulated to compute a field offset. rdar://problem/28992749 (cherry picked from commit 638fa2b35af426deff7e3b8f75d0be69df8f7130)
