[PATCH] D57984: PR40642: Fix determination of whether the final statement of a statementexpression is a discarded-value expression.

[Richard Smith - zygoloid via Phabricator via cfe-commits]

rsmith updated this revision to Diff 186578.
rsmith added a comment.

Combine WithinStmtExpr flag with AllowedStmtKinds into a more general statement
context. In doing so, fix some bugs where the OpenMP context was not being
propagated properly through labels and expression-statements starting with @.
