If I build and run the tests (`ninja check-clang check-llvm`) near head (`commit 259ce1199906554fba5c8d3b07b6ce14ee42d301`)
with Visual Studio 17.10.3 on a Windows ARM64 machine (using the arm64 native cl.exe, no emulation), I get a large number of test assert failures:
```
$ mkdir build
$ cd build
$ cmake -G Ninja -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_ENABLE_PROJECTS=clang ..\llvm
$ ninja check-clang check-llvm
...
Total Discovered Tests: 60182
Skipped : 28 (0.05%)
Unsupported : 1527 (2.54%)
Passed : 58150 (96.62%)
Expectedly Failed: 166 (0.28%)
Failed : 311 (0.52%)
```
Here are the `sort|uniq`'d assert failures from the test run:
```

Assertion failed: getAlign() && *getAlign() == Align && "Alignment representation error!", file C:\Users\hiroshi\llvm-project\llvm\lib\IR\Globals.cpp, line 144
```
I started looking into this because the Swift toolchain build (using downstream `swiftlang/llvm-project`) seems to result in similar assert failures with VS 17.10.3.
