Return back "[SYCL][L0] Support DPC++ extension Queue Order Properties. (intel#3396)" reverted earlier in (intel#3479)
Added fix for the segfault happening due to wait on an already released event.
The related test SYCL/InorderQueue/in_order_event_release.cpp is added in llvm-test-suite.

[SYCL] Replace spec constants 2020 with RT-provided values in sycl-po…

…st-link (intel#3430)

By doing this change, SpecConstantsPass starts to replace scalar specialization
constants with a user-provided value from RT (instead of using C++ default
initialization value) for AOT mode.

This is done with the new intrinsic __sycl_getScalar2020SpecConstantValue:
the 3rd argument RTBuffer is a pointer to a runtime buffer, which holds
values of all specialization constants.

[SYCL][NFC] Fix kernel_lambda_with_kernel_handler_arg.cpp test (intel…

…#3467)

This patch avoids running this test on the host device as spec constants
for host device are not implemented yet. Instead, it runs with OpenCL CPU
because low-level runtime and devices are not important here - the impl
is backend-agnostic.

[ESIMD] Let ESIMD attributes not depend on -fsycl-explicit-simd (inte…

…l#3446)

This is one of the final patches to support mixing SYCL and ESIMD kernels.
In the end, we want to get rid of `-fsycl-explicit-simd` option and unify the two modes: regular SYCL and ESIMD.
This patch eliminates one of the dependencies on the `-fsycl-explicit-simd` flag, allowing to use ESIMD attributes without it.

[SYCL][FPGA] Update LSU builtins template to allow multi_ptr (intel#3321

)

Updated LSU headers to allow multi_ptr instead of global_ptr.
Added address space checks to builtins.

[SYCL][FPGA] Drop the duplicate attribute when adding or merging (int…

…el#3389)

This patch drops a duplicate attribute when adding or merging for FPGA attributes below:

1. [[intel::private_copies()]
2. [[intel::max_replicates()]]
3. [[intel::reqd_sub_group_size()]]
4. [[intel::num_simd_work_items()]]
5. [[intel::loop_fuse()]]
6. [[intel::loop_fuse_independent()]]
7. [[intel::no_global_work_offset()]]
8. [[intel::scheduler_target_fmax_mhz()]]

Also adds tests for each of the attributes with duplicate arguments.
