Allan Shortlidge	164ac421d6	Sema: Lift restriction preventing use of #_hasSymbol on non-Darwin platforms. ... An early approach to codegen for `#_hasSymbol` relied on the Darwin platfom SDK, but now that the feature lowers directly to NULL checks in LLVM IR a platform restriction is no longer needed. However, the tests for `#_hasSymbol` remain unsupported on Windows since that OS does not support weak linking.	2022-11-30 14:58:28 -08:00
