The following patch adds the missing
{unsigned ,}__int128 <-> _Decimal{32,64,128}
conversion support into libgcc.a on top of the _BitInt support
(doing it without that would be larger amount of code and I hope all
the targets which support __int128 will eventually support _BitInt,
after all it is a required part of C23) and because it is in libgcc.a
only, it doesn't hurt that much if it is added for some architectures
only in GCC 15.
Initially I thought about doing this on the compiler side, but doing
it on the library side seems to be easier and more -Os friendly.
The tests currently require bitint effective target, that can be
removed when all the int128 targets support bitint.
