spirv: Properly handle SpvOpAtomicCompareExchangeWeak
The code was handling the Weak variant in some cases, but missing
others, e.g. the get_deref_nir_atomic_op. Add all the missing cases
with the same behavior of the non-Weak SpvOpAtomicCompareExchange.
Note that the Weak variant is basically an alias, as SPIR-V 1.3,
Revision 7 says
"OpAtomicCompareExchangeWeak
Deprecated (use OpAtomicCompareExchange).
Has the same semantics as OpAtomicCompareExchange."
