<intrin.h>: clang-tidy and "expected function body after function declarator" #1300
Description
Describe the bug
After updating to 16.8.0 Preview 3, I've been getting strange errors from Clang-Tidy. Fearing it was some weird interaction between my MSBuild config, .clang-tidy, the Unity build, or project structure, I tried a simple x64 console project right from the templates and managed to get the same error:
Build started...
1>------ Build started: Project: ClangTidyIssue, Configuration: Debug x64 ------

Suppressed 1 warnings (1 in non-user code).
Use -header-filter=.* to display errors from all non-system headers. Use -system-headers to display errors from system headers as well.
Found compiler error(s).

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
Command-line test case
Just create a new Console Application, Enable Code Analysis on build and Clang-Tidy, build in x64/Debug.
Expected behavior
No compile failures ([clang-diagnostic-error]) every time intrin.h is included.
