Generate nuw GEPs for struct member accesses, as inbounds + non-negative implies nuw. Regression tests are updated using update scripts where possible, and by find + replace where not.

This adds -no-opaque-pointers to clang tests whose output will change when opaque pointers are enabled by default. This is intended to be part of the migration approach described in https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9. The patch has been produced by replacing %clang_cc1 with %clang_cc1 -no-opaque-pointers for tests that fail with opaque pointers enabled. Worth noting that this doesn't cover all tests, there's a remaining ~40 tests not using %clang_cc1 that will need a followup change. Differential Revision: https://reviews.llvm.org/D123115
EHTerminateScope is used to implement C++ noexcept semantics. Per C++ [except.terminate], it is implemented-defined whether no, some, or all cleanups are run prior to terminatation. Therefore, the code to run cleanups on the way towards termination is unnecessary, and may be omitted. After this change, we will still run some cleanups: any cleanups in a function called from the noexcept function will continue to run, while those in the noexcept function itself will not. (Commit attempt 2: check InnermostEHScope != stable_end() before accessing it.) Differential Revision: https://reviews.llvm.org/D113620
Breaks tests on some platforms. Reverting while investigating. This reverts commit a4e255f9c6d4458fa6e70394af626f3b65e0a26d.

Add support for ordered directive in the OpenMPIRBuilder. This patch also modidies clang to use the ordered directive when the option -fopenmp-enable-irbuilder is enabled. Also fix one ICE when parsing one canonical for loop with the relational operator LE or GE in openmp region by replacing unary increment operation of the expression of the variable "Expr A" minus the variable "Expr B" (++(Expr A - Expr B)) with binary addition operation of the experssion of the variable "Expr A" minus the variable "Expr B" and the expression with constant value "1" (Expr A - Expr B + "1").

Summary: The OpenMP loops are normalized and transformed into the loops from 0 to max number of iterations. In some cases, original scheme may lead to overflow during calculation of number of iterations. If it is unknown, if we can end up with overflow or not (the bounds are not constant and we cannot define if there is an overflow), cast original type to the unsigned.

IR. Fixed a crash because of the not quite correct casting of the value of iterations.
induction variable abends. Used incorrect loop bound when trying to calculate the index in the vec array for doacross construct in the loops with the reverse order.
