Intl constructors are specified to prohibit structurally invalid subtags. BCP 47 defines itself to be case-insensitive. Firefox does throw on case-insensitive duplicates, following the specifications. This patch makes V8 do the same. There is some small compatibility risk, but the case is fairly niche, so I hope it does not cause much breakage.
