[NFCI][SimplifyCFG] Mark all the SimplifyCFG tests that already don't invalidate DomTree as such First step after e1133179587dd895962a2fe4d6eb0cb1e63b5ee2, in these tests, DomTree is valid afterwards, so mark them as such, so that they don't regress. In further steps, SimplifyCFG transforms shall taught to preserve DomTree, in as small steps as possible.

[IR] Convert null-pointer-is-valid into an enum attribute The "null-pointer-is-valid" attribute needs to be checked by many pointer-related combines. To make the check more efficient, convert it from a string into an enum attribute. In the future, this attribute may be replaced with data layout properties.
