[PATCH] Fix PR62190

[Richard Biener]

The C frontend commonizes uint{16,32,64}_type_node with existing
integer type nodes and thus gets proper "names" for them.  The
LTO frontend (and tree.c common code) keeps them separate
and thus debugs as __unknown__.  The following patch arranges
the common code in build_common_tree_nodes to use
make_or_reuse_type for those.

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

Richard.
