Nikita Popov a290f3c8fc [OpenMP] Convert tests to opaque pointers (NFC) 
Conversion performed using the script at:
https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34

These are only tests where no manual fixup was required.

Nikita Popov 532dc62b90 [OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC) 
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.

CJ Johnson 69cd776e1e [CodeGen] Apply 'nonnull' and 'dereferenceable(N)' to 'this' pointer 
arguments.

* Adds 'nonnull' and 'dereferenceable(N)' to 'this' pointer arguments
* Gates 'nonnull' on -f(no-)delete-null-pointer-checks
* Introduces this-nonnull.cpp and microsoft-abi-this-nullable.cpp tests to
  explicitly test the behavior of this change
* Refactors hundreds of over-constrained clang tests to permit these
  attributes, where needed
* Updates Clang12 patch notes mentioning this change

Alexey Bataev 43101d10db [OPENMP50]Codegen for scan directive in simd loops. 
Added codegen for scan directives in simd loop. The codegen transforms
original code:
```
int x = 0;
 #pragma omp simd reduction(inscan, +: x)
for (..) {
  <first part>
  #pragma omp scan inclusive(x)
  <second part>
}
```
into
```
int x = 0;
for (..) {
  int x_priv = 0;
  <first part>
  x = x_priv + x;
  x_priv = x;
  <second part>
}
```
and
```
int x = 0;
 #pragma omp simd reduction(inscan, +: x)
for (..) {
  <first part>
  #pragma omp scan exclusive(x)
  <second part>
}
```
into
```
int x = 0;
for (..) {
  int x_priv = 0;
  <second part>
  int temp = x;
  x = x_priv + x;
  x_priv = temp;
  <first part>
}
```
