This extension advertises the SPIR-V *Int64Atomics* capability for Vulkan,
which allows a shader to contain 64-bit atomic operations on signed and
unsigned integers.
The supported operations include OpAtomicMin, OpAtomicMax, OpAtomicAnd,
OpAtomicOr, OpAtomicXor, OpAtomicAdd, OpAtomicExchange, and
OpAtomicCompSwap.
