gdb: BigPtrArrayPrinter gets confused by libstdc++ std::unique_ptr

It looks like this in libstdc++:

<BigPtrArray> = {
m_ppInf = {
_M_t = {
<std::__uniq_ptr_impl<BlockInfo*, std::default_delete<BlockInfo* []> >> = {
_M_t = {
<std::_Tuple_impl<0, BlockInfo**, std::default_delete<BlockInfo* []> >> = {
<std::_Tuple_impl<1, std::default_delete<BlockInfo* []> >> = {
<std::_Head_base<1, std::default_delete<BlockInfo* []>, true>> = {
_M_head_impl = {<No data fields>}
}, <No data fields>},
<std::_Head_base<0, BlockInfo**, false>> = {
_M_head_impl = 0x567fd20
}, <No data fields>}, <No data fields>}
}, <No data fields>}
},

Note there are 2 _M_head_impl members, and somehow gdb 11.1-2.fc34 picks
the wrong one.

A manual cast to std::_Head_base<0, BlockInfo**, false> seems to help.
