[SYCL] Update tests with -fno-sycl-id-queries-fit-in-int option

[smanna12]

The changes are due to the PR: intel/llvm#3427

The failures seem unrelated to my change.

[AlexeySachkov]

I wonder, why those changes are needed at all?

[smanna12]

Thanks @AlexeySachkov for reviewing the patch.

intel/llvm#3427: Enables the option -fsycl-id-queries-fit-in-int to true by default. sub_group_as.cpp passes when the option is false on default mode but fails with default ON. So I added -fno-sycl-id-queries-fit-in-int to disable the option and match with the old behavior.

sycl-id-queries-fit-in-int makes a big impact on performance for DPC++ in many cases. The test failures currently block intel/llvm#3427. Is there any workaround i can use here? Thanks.

It looks like root cause for failing test is the same with post-commit failures after merging intel/llvm#3427

@vladimirlaz, PR: intel/llvm#3427: which has not been merged yet. I am waiting for this PR to be merged first before merging PR: intel/llvm#3427

@smanna12, please create issue for the regression. It looks like the test start to fail after changing default behavior.
In short: load/store functions for local pointer stop work as expected.

@vladimirlaz, I have created intel/llvm#3495 for the regression and assigned to you. Thanks.
