error: explicit comparison with infinity in fast floating point mode [-Werror,-Wtautological-constant-compare]

[TApplencourt]

When building the repo with icpx the test_case/test_case_statistics.cpp compile fail with

 error: explicit comparison with infinity in fast floating point mode [-Werror,-Wtautological-constant-compare]

Possible solution:

• Disable tautological-constant-compare
• Set -00 flags globally
• Disable fast-math for the particulars files

With oneAPI 2023.0, there are more issues:

icpx: error: use of 'dpcpp' is deprecated and will be removed in a future release. Use 'icpx -fsycl' [-Werror,-Wdeprecated]

as well as multiple SYCL-related deprecation warnings like

/home/aland/compute-benchmarks/source/framework/sycl/sycl.h:22:22: warning: 'device_selector' is deprecated: Use SYCL 2020 callable device selectors instead. [-Wdeprecated-declarations]

/home/aland/compute-benchmarks/source/framework/sycl/utility/print_device_info_sycl.inl:27:21: warning: 'host' is deprecated: 'host' backend is no longer supported [-Wdeprecated-declarations]

and generic "compiler confused by testing framework" warnings like

/home/aland/compute-benchmarks/source/benchmarks/memory_benchmark/gtest/usm_copy_immediate.cpp:13:56: warning: unused variable 'registerTestCase' [-Wunused-const-variable]
