Zhaoming Jiang 4faf3581b8 Tint/builder/spirv: Fix atomicCompareExchangeWeak wrong return
This CL fix the spv code generated for atomicCompareExchangeWeak,
specifically the emulated `exchanged` field of the returned struct.
It should be true if and only if the `old_value`, i.e. the return value
of spv `OpAtomicCompareExchange`, equals to the comparator, rather than
equals to new value.

Fixed: tint:1663
