Merge #18553: Avoid non-trivial global constants in SHA-NI code 
850847309458f43fc7ce6c13fa08c86e1cae042a Avoid non-trivial global constants in SHA-NI code (Pieter Wuille)

Pull request description:

  This is a potential solution for #18456.

  It seems that the compiler cannot turn `_mm_set_epi64x(<constant>,<constnant>)` into a constant itself, and thus emits a global initializer for the `MASK`, `INIT0`, and `INIT1` global constants in the sha-ni SHA256 implementation.

  Change this by turning them into dumb byte arrays, loading them into an SSE variable whenever needed.

  Tested on a SHA-NI capable machine. I do not observe any obvious performance impact (but this is hard to measure, it's already very fast...).
