Instead, the value of ``GETPC()`` should be read from the helper and passed if needed to the functions that the helper calls. Let's fix the GETPC() usage in Hexagon, making sure it's always called from top level helpers and passed down to the places where it's needed. There are a few snippets where that is not currently the case: - probe_store(), which is only called from two helpers, so it's easy to move GETPC() up. - mem_load*() functions, which are also called directly from helpers, but through the MEM_LOAD*() set of macros. Note that this are only used when compiling with --disable-hexagon-idef-parser. In this case, we also take this opportunity to simplify the code, unifying the mem_load*() functions. - HELPER(probe_hvx_stores), when called from another helper, ends up using its own GETPC() expansion instead of the top level caller.
