Antonio Maiorano 268d7b8357 tint: Add support for atomic ops to spirv reader
The following operations are supported:

OpAtomicLoad
OpAtomicStore
OpAtomicExchange
OpAtomicCompareExchange
OpAtomicCompareExchangeWeak
OpAtomicIIncrement
OpAtomicIDecrement
OpAtomicIAdd
OpAtomicISub
OpAtomicSMin
OpAtomicUMin
OpAtomicSMax
OpAtomicUMax
OpAtomicAnd
OpAtomicOr
OpAtomicXor

These are not, but may be supported in the future:

OpAtomicFlagTestAndSet
OpAtomicFlagClear
OpAtomicFMinEXT
OpAtomicFMaxEXT
OpAtomicFAddEXT
