6ff380f439 [OpenMP][NFC] Remove SIMD check lines for non-simd tests
If a test does not contain an " simd" but -fopenmp-simd RUN lines we can
just check that we do not create __kmpc|__tgt calls.

Return "[CGCall] Annotate this argument with alignment"
The original change was reverted because it was discovered
that clang mishandles thunks, and they receive wrong
attributes for their this/return types - the ones for the function
they will call, not the ones they have.

While i have tried to fix this in https://reviews.llvm.org/D100388
that patch has been up and stuck for a month now,
with little signs of progress.

So while it will be good to solve this for real,
for now we can simply avoid introducing the bug,
by not annotating this/return for thunks.

This reverts commit 6270b3a1eafaba4279e021418c5a2c5a35abc002,
relanding 0aa0458f1429372038ca6a4edc7e94c96cd9a753.

207b08a913 [OpenMP][NFC] Refactor Clang OpenMP tests using update_cc_test_checks
This patch refactors a subset of Clang OpenMP tests, generating checklines using the update_cc_test_checks script. This refactoring facilitates updating the Clang OpenMP code generation codebase by automating test generation.

Fix the many cases of use of undefined SIVAR/SVAR/SFVAR in OpenMP
*private_codegen tests, due to a missing BLOCK directive to capture the
IR variable when it is declared. It also fixes a few typo in its use.

6b3351792c [test] Add {{.*}} to make tests immune to dso_local/dso_preemptable/(none) differences
For a definition (of most linkage types), dso_local is set for ELF -fno-pic/-fpie
and COFF, but not for Mach-O.  This nuance causes unneeded binary format differences.

This patch replaces (function) `define ` with `define{{.*}} `,
(variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `
if there is an explicit linkage.

* Clang will set dso_local for Mach-O, which is currently implied by TargetMachine.cpp. This will make COFF/Mach-O and executable ELF similar.
* Eventually I hope we can make dso_local the textual LLVM IR default (write explicit "dso_preemptable" when applicable) and -fpic ELF will be similar to everything else. This patch helps move toward that goal.

constructs. Some of the clauses, like 'grainsize', 'num_tasks', 'final'
and 'priority' are not supported in full, only constant expressions can
be used currently in these clauses.
