Summary
Adds (unboxed) Generic protocol conformance for UUID and Date.
UUIDuses aSIMD16<UInt8>raw representation, which matches the internaluuid_ttype of a 16-wide tuple. I also triedUInt128(macOS 15+) orSIMD2<UInt64>, but when loading the values (for copying in-out of the array) Swift/LLVM is smart enough to just do so as a singleSIMD2<UInt64>in all cases.Dategoes via the time interval since reference date so should be a no-op.
