Auto merge of #90208 - Mark-Simulacrum:hash-bytes-fast, r=oli-obk
Specialize HashStable for [u8] slices Particularly for ctfe-stress-4, the hashing of byte slices as part of the MIR Allocation is quite hot. Previously, we were falling back on byte-by-byte copying of the slice into the SipHash buffer (64 bytes long) before hashing a 64 byte chunk, and then doing that again and again; now we use the dedicated byte-slice write.
