martinboehme 0362a29905 [clang][dataflow] Fix bug in buildContainsExprConsumedInDifferentBlock(). (#100874) ...

This was missing a call to `ignoreCFGOmittedNodes()`. As a result, the
function
would erroneously conclude that a block did not contain an expression
consumed
in a different block if the expression in question was surrounded by a
`ParenExpr` in the consuming block. The patch adds a test that triggers
this
scenario (and fails without the fix).

To prevent this kind of bug in the future, the patch also adds a new
method
`blockForStmt()` to `AdornedCFG` that calls `ignoreCFGOmittedNodes()`
and is
preferred over accessing `getStmtToBlock()` directly.
