Hi,
while looking into the PR testcase I noticed that we detect wrong duplicate
types. This is because we compute DECL_ASSEMBLER_NAME of a type variant which
is not necessary.
Bootstrapped/regested x86_64-linux and I checked dumps of xalancbmk to verify
that nothing changes in ODR type merging except for the duplicates. OK?

variabt types.
