https://github.com/llvm/llvm-project/pull/171941 made the builtins tests run when configured as part of a "runtimes build" (`-DLLVM_ENABLE_RUNTIMES=...`).
As reported in https://github.com/llvm/llvm-project/pull/174443#issuecomment-3729604341, not all of the tests pass on Mac and Windows. Specifically, when building with `-DCOMPILER_RT_BUILD_CRT=ON` some tests with `// REQUIRES: crt` will fail due to unsupported flags or missing `crt1.o` etc.
See below for the failures.
Presumably these tests were never meant to run on Mac or Windows? Should we mark them unsupported? `REQUIRES: linux`?

When configuring and building with
```
cmake -GNinja -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS=clang -DLLVM_TARGETS_TO_BUILD=Native -DLLVM_ENABLE_RUNTIMES=compiler-rt -DCOMPILER_RT_BUILD_CRT=ON ../llvm
ninja check-runtime
```
On arm64 Mac:

dso_handle.cpp also failed on x64 Mac. It didn't run on arm64 because of `// UNSUPPORTED: target={{(arm|aarch64).*}}`
