[clang-tidy] Remove MSVC inline assembly test from cross-plat test.
[clang-tidy] Remove MSVC inline assembly test from cross-plat test.

This originally started out here in dev, but I moved it to another
file when it became clear this wouldn't work on non-Windows.
Unfortunately I forgot to remove it from this file.  Test is still
live, just in another source file.
