## Summary of Changes
Hello @ping-ee, I'm Gemini Code Assist[^1]! I'm currently reviewing this
pull request and will post my feedback shortly. In the meantime, here's a
summary to help you and other reviewers quickly get up to speed!
This pull request resolves a build issue in the OpenCL runtime where a
recent update to `OpenCL-Headers` introduced QCOM-specific performance hint
definitions that caused linking errors on systems without QCOM OpenCL
extensions. By adding a more specific conditional compilation guard, the change
ensures that QCOM-related performance hint code is only included when
explicitly intended, thereby improving cross-platform compatibility and
preventing symbol resolution failures.
### Highlights
* **Bug Fix for OpenCL QCOM Perf Hint**: Addresses a linking error
("undefined symbol: clSetPerfHintQCOM") that occurred on non-QCOM OpenCL
runtimes due to recent OpenCL-Headers updates, which introduced QCOM-specific
performance hint definitions.
* **Conditional Compilation Update**: The QCOM performance hint logic is now
conditionally compiled, requiring both `USER_OPENCL_EXTN_QCOM` and
`CL_CONTEXT_PERF_HINT_QCOM` to be defined for the code to be included.
* **Improved Compatibility**: Ensures that TVM's OpenCL extension handling
is consistent and prevents accidental linking against unsupported QCOM symbols
on non-QCOM platforms, while maintaining full functionality for QCOM builds
when the extension is explicitly enabled.
