gcc14-bitint-wip.patch
Actually implemented support for switches first. The switchlower support pass
has most of the support, so all we need is if we detect large/huge _BitInt
indexed switch is to lower it at the start of the bitintlower pass with small
tweak in the switchlower pass
to transform jump tables from ones indexed by large/huge _BitInt into ones
indexed by unsigned long long; switchlower never creates clusters with range
which doesn't fit into 64 bits, which makes this possible.
