[PR lto/77458] Avoid ICE in offloading with differing _FloatN, _FloatNx types
gcc/
PR lto/77458
* tree-core.h (enum tree_index): Put the complex types after their
component types.
* tree-streamer.c (verify_common_node_recorded): New function.
(preload_common_nodes) <TREE_CODE (node) == COMPLEX_TYPE>: Use it.
