Rollup merge of #43480 - dhduvall:sparc-blake2b, r=eddyb
Constrain the layout of Blake2bCtx for proper SPARC compilation On SPARC, optimization fuel ends up emitting incorrect load and store instructions for the transmute() call in blake2b_compress(). If we force Blake2bCtx to be repr(C), the problem disappears. Fixes #43346
