Added documentation to the ir context to indicates that TakeNextId() returns 0 when the max id is reached. TODOs were added to each call sight so that we know where we have to start to handle this case. Handle id overflow in |SplitLoopHeader|. Handle id overflow in |GetOrCreatePreHeaderBlock|. Handle failure to create preheader in LICM. Part of https://github.com/KhronosGroup/SPIRV-Tools/issues/1841.
