  Log Message:
  -----------
  [OpenMP] Introduce the ompx_name clause for kernel naming

This adds support for the ompx_name clause that allows users to specify
custom kernel names for OpenMP target offloading regions. The clause
accepts a string literal and overrides the default compiler-generated
kernel names.

Example usage:
  #pragma omp target ompx_name("my_kernel")
  { ... }

In the process, the linkage of the offload entries was changed from weak
to external (for kernels), or whatever the global variable linkage is.
This makes sure we can link weak globals together but clash on kernels
with the same name.
