[SYCL] SYCL 2020 standalone device selectors ( gpu_selector_v and friends)

3

implementation of standalone selectors (e.g. gpu_selector_v, etc) new tests for llvm-test-suite are here: https://github.com/intel/llvm-test-suite/pull/1141

[SYCL] ONEAPI_DEVICE_SELECTOR implementation

3

Functionally complete. Needs tests and possible reorganization.

bfloat16 type reinterpretation may cause problems when aggressive optimizations are employed. Splitting them off to avoid this.

[SYCL] test update: support single tile PVC

2

A few of our tests assume that a given PVC installation always has multiple tiles available, which is not true. Putting appropriate guards into those tests.

PVC 1T systems have some issues with partitioning. Disabling these tests on those systems while awaiting driver fixes.

[SYCL] no exceptions leaking from destructors

1

Destructors are implicitly noexcept, so we must ensure they don't actually throw exceptions. No change to API or ABI with this PR.

SYCL language support on the part of the kernel_compiler is specified here: https://github.com/intel/llvm/pull/11985 However, that specification is not presently realizable. We need more support from the FE and post link...

[POC] [DO NOT MERGE/JUDGE] std::nan support cmath in device only code.

1

Some users are wanting to reuse kernel code that contains `std::nan("str");` declarations. At first I thought this impossible. But then...

This PR proposes a new extension for a `wait` that sleeps rather than running CPU full tilt, as has been requested for IoT and similar applications. Because it is fairly...

[SYCL] adding binary caching support to kernel_compiler extension

1

Trying to reuse as much of the `PersistentDeviceCodeCache` as possible. We use the same top cache directory as the regular binary caches, but with a `ext_kernel_compiler` subdirectory and a slightly...
