layers: More efficient cb_bindings to object_bindings linking

Previously this code did a hash table lookup (and insertion if not
present) followed by a second hash table lookup and insertion. Swap
the order of the checks and check the smaller table (cb_bindings)
first, and use a small_unordered_map for it. This makes there
usually be no hash lookup on the first table. Then replace the
second table with a vector, and just push_back instead of doing a
hash table insertion (each object can only be in this table once).
So now, the majority of the time, no hashing and no memory allocation.

Store a BASE_NODE pointer in VulkanTypedHandle, which can be used to
skip the hash table lookup if it's present.

Introduction

Vulkan is an Explicit API, enabling direct control over how GPUs actually work. By design, minimal error checking is done inside a Vulkan driver. Applications have full control and responsibility for correct operation. Any errors in how Vulkan is used can result in a crash. This project provides Vulkan validation layers that can be enabled to assist development by enabling developers to verify their applications correct use of the Vulkan API.

The following components are available in this repository:

How to Build and Run

BUILD.md Includes directions for building all components as well as running validation tests.

Information on how to enable the various Validation layers is in layers/README.md.

Version Tagging Scheme

Updates to the Vulkan-ValidationLayers repository which correspond to a new Vulkan specification release are tagged using the following format: v<version> (e.g., v1.1.96).

Note: Marked version releases have undergone thorough testing but do not imply the same quality level as SDK tags. SDK tags follow the sdk-<version>.<patch> format (e.g., sdk-1.1.92.0).

This scheme was adopted following the 1.1.96 Vulkan specification release.
