alpha: xchg/cmpxchg cleanup and fixes
- "_local" versions of xchg/cmpxchg functions duplicate code
of non-local ones (quite a few pages of assembler), except
memory barriers. We can generate these two variants from a
single header file using simple macros;
- convert xchg macro back to inline function using always_inline
attribute;
- use proper argument types for cmpxchg_u8/u16 functions
to fix a problem with negative arguments.
