Reimplement __builtin_unique_stable_name- The original version of this was reverted, and @rjmcall provided some advice to architect a new solution. This is that solution. This implements a builtin to provide a unique name that is stable across compilations of this TU for the purposes of implementing the library component of the unnamed kernel feature of SYCL. It does this by running the Itanium mangler with a few modifications. Because it is somewhat common to wrap non-kernel-related lambdas in macros that aren't present on the device (such as for logging), this uniquely generates an ID for all lambdas involved in the naming of a kernel. It uses the lambda-mangling number to do this, except replaces this with its own number (starting at 10000 for readabililty reasons) for lambdas used to name a kernel. Additionally, this implements itself as constexpr with a slight catch: if a name would be invalidated by the use of this lambda in a later kernel invocation, it is diagnosed as an error (see the Sema tests).

Change __builtin_sycl_unique_stable_name to just use an Itanium mangling After significant problems in our downstream with the previous implementation, the SYCL standard has opted to make using macros/etc to change kernel-naming-lambdas in any way UB (even passively). As a result, we are able to just emit the itanium mangling. However, this DOES require a little work in the CXXABI, as the microsoft and itanium mangler use different numbering schemes for lambdas. This patch adds a pair of mangling contexts that use the normal 'itanium' mangling strategy to fill in the "DeviceManglingNumber" used previously by CUDA.

This implements a builtin to provide a unique name that is stable across compilations of this TU for the purposes of implementing the library component of the unnamed kernel feature of SYCL. It does this by running the Itanium mangler with a few modifications. Because it is somewhat common to wrap non-kernel-related lambdas in macros that aren't present on the device (such as for logging), this uniquely generates an ID for all lambdas involved in the naming of a kernel. It uses the lambda-mangling number to do this, except replaces this with its own number (starting at 10000 for readabililty reasons) for lambdas used to name a kernel. Additionally, this implements itself as constexpr with a slight catch: if a name would be invalidated by the use of this lambda in a later kernel invocation, it is diagnosed as an error (see the Sema tests).
