Validator support for Variable Pointer extension.
If the variable_pointer extension is used:
* OpLoad's pointer argument may be the result of any of the following:
* OpSelect
* OpPhi
* OpFunctionCall
* OpPtrAccessChain
* OpCopyObject
* OpLoad
* OpConstantNull
* Return value of a function may be a pointer.
* It is valid to use a pointer as the return value of a function.
* OpStore should allow a variable pointer argument.
