DF mangling


Hi!

The Itanium C++ ABI defines
https://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling-builtin
DF<number>_ as the mangling for the <number> bit IEEE binary float type,
i.e. _Float<number>.

But the libiberty unwinders decode DF<something> as fixed point type, see
https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=libiberty/cp-demangle.c;h=3f2a097e7f2075e5750e40a31ce46589d4ab83d5;hb=HEAD#l2659

This conflicts.  How are we going to resolve it?
