/*
* Work around an issue with --enable-lto, in which GCC's ipa-split pass
* decides to split out the noreturn code paths that raise an exception,
* taking the __builtin_return_address() along into the new function,
* where it no longer computes a value that returns to TCG generated code.
* Despite the name, the noinline attribute affects splitter, so this
* prevents the optimization in question. Given that helpers should not
* otherwise be called directly, this should have any other visible effect.
*
