Description
Description
We set this test to skip when running under x64 emulation on arm64 with this PR:
https://github.com/microsoft/DirectXShaderCompiler/pull/8794#pullrequestreview-4956395551
But upon review we realized there could be an x64 emulation bug here. The PR is approved to help skip the test for now. But a follow-up review is needed to root cause whats actually going on here. The test passes on x64.

Research direction
Start with the CodeGenFloatingPointEnvironment test and the skip change in PR 8794, then compare its behavior on x64 with x64 emulation on ARM64. Determine the cause of the emulation-specific failure and document or implement a verified resolution so the test no longer needs an unexplained skip.
