Inlining performs a wrong non-call exception fixup for VEC_COND_EXPRs
which on the branch fail to properly have the condition split out in
the first place.

Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed to
the GCC 10 branch which is the only one this code snippet prevails.

        * tree-inline.c (remap_gimple_stmt): Use correct type for
        split out condition of [VEC_]COND_EXPRs.
