[SYCL] Add '--ignore-device-selectors' CLI option to sycl-ls and improve warning messages

4

This PR adds a '--ignore-device-selectors' CLI option to sycl-ls that prints all platforms available in the user's system, irrespective of the DPCPP filter environment variables like ONEAPI_DEVICE_SELECTOR.

As per discussion in https://github.com/intel/llvm/issues/12632, this PR updates SYCL_DEVICE_ALLOWLIST documentation to also allow 'fpga' as a valid device type. PR https://github.com/intel/llvm/pull/12614 already implemented this change.

[SYCL] Several tests failed with OpenCL FPGA in precommit

**Describe the bug** Testing in #12673 shows the following tests failed with opencl:fpga. Assert tests failed because the tests did not produce the desired output. _Affected tests_: ~~Assert/assert_in_kernels.cpp~~ ~~Assert/assert_in_multiple_tus.cpp~~ ~~Assert/assert_in_multiple_tus_one_ndebug.cpp~~...

Align terminology used by ONEAPI_DEVICE_FILTER and SYCL_DEVICE_ALLOWLIST

4

Currently, SYCL_DEVICE_ALLOWLIST uses 'acc' to select accelerator device type while ONEAPI_DEVICE_FILTER uses 'fpga' for the same. I propose that we also update SYCL_DEVICE_ALLOWLIST to use 'fpga' instead of 'acc'. Not...

[SYCL] Use std::array as storage for syc::vec on device

2

Changing the storage to `std::array` instead of Clang's extension fixes strict ansi-alising violation and simplifies device code. This PR also cleans up `sycl::vec` code.
