Merge stable (#15429)
* druntime: Restrict some `pragma(inline, false)` kludges to DMD only

They appear related to DMD's inlining at the AST level; LDC at least
doesn't need them, so let the optimizer decide for non-DMD backends.

* Fix little C++ header regression

* Expose VarArg.KRvariadic to C++ headers

* Revert "Deprecate alias this for classes v2 (#14812)" (#15326)

This reverts commit af7817b4ae.

* Add changelog for catch qualifier deprecation & update release no
