> Should be fixed on all active branches.

Actually the backport to gcc-6-branch introduced a regression. On arm, I'm
seeing:
lto1: fatal error: missing resolution data for _ZTV4base
compilation terminated.
lto-wrapper: fatal error:
/aci-gcc-fsf/builds/gcc-fsf-gccsrc/obj-arm-none-linux-gnueabihf/gcc3/gcc/testsuite/g++2/../../xg++
returned 1 exit status
compilation terminated.
/aci-gcc-fsf/builds/gcc-fsf-gccsrc/tools/arm-none-linux-gnueabihf/bin/ld:
error: lto-wrapper failed
collect2: error: ld returned 1 exit status
compiler exited with status 1

On aarch64, one of the testcases now produces an ICE:
