gcc14-bitint-wip.patch
Further updates. This introduces a new bitintlower (and bitintlower0) pass,
categorizes
_BitInt types into 4 categories (small, which are kept as is as they work out
of the box, middle, which have already more than one limb, but there exists
DImode or TImode
type which is supported and covers the precision, here lowering is done by
casting to
INTEGER_TYPE and back, large which is up to double that size (so it will be
lowered to straight line code) and huge, which will use loops. The lowering is
so far implemented for the middle _BitInts.
Added some runtime testsuite coverage for the small and middle _BitInts (so on
x86-64 up to 128 bits).
