c++: #pragma target and deferred instantiation [PR115403]
My patch for 109753 applies the current #pragma target/optimize to a
function when we compile it, which was a problem for a template
instantiation deferred until EOF, where different #pragmas are active. So
let's only do this for artificial functions.

PR c++/109753
gcc/cp/ChangeLog:
* decl.cc (start_preparsed_function): Only call decl_attributes for
artificial functions.
gcc/testsuite/ChangeLog:
* g++.dg/ext/pragma-target1.C: New test.
