=== Description

This extension allows a shader to contain floating-point atomic operations
on buffer, workgroup, and image memory.
It also advertises the SPIR-V code:AtomicFloat32AddEXT and
code:AtomicFloat64AddEXT capabilities that allows atomic addition on
floating-points numbers.
The supported operations include code:OpAtomicFAddEXT,
code:OpAtomicExchange, code:OpAtomicLoad and code:OpAtomicStore.
