The location index of a vertex shader input's layout qualifier must be
less than GL_MAX_VERTEX_ATTRIBS to link successfully. We can check for
this during shader compilation to not rely on other layers to handle
pathological cases.

While strictly speaking only 'active' attributes are considered during
shader linking, this is merely intended to allow for 'uber' shaders to
declare more inputs than GL_MAX_VERTEX_ATTRIBS but only use a subset of
them. There is no known reasonable use case for a manually specified
location to exceed the valid range.

Note that according to http://opengl.gpuinfo.org, the highest
GL_MAX_VERTEX_ATTRIBS value at the time of writing is 32. Also,
D3D12_VS_INPUT_REGISTER_COUNT = 32. Hence the unit test's value of 1000
should be sufficiently future proof.

Also address the case where the uniform location might be close to
INT_MAX and not be detected as out-of-range due to numeric overflow.

XWayland defaults to a 1hz refresh rate when the surface is not
visible, but this can sometimes cause issues in Chrome. If we see
a bogus rate like that, ANGLE can just report 30hz.

This reduces preferredLargeHeapBlockSize from the default
value of 256 MB to 4 MB, which reduces the initial block
size from 32 MB to 512 KB.

4 MB is the same size as used by Chromium and Skia. It seems
to be a good compromise of not wasting unused allocated space
and not making too many small allocations.

This change is limited to non-Qualcomm GPUs as a number of
tests are failing on Qualcomm after this change and the
initial investigation indicates a potential driver bug. See
http://anglebug.com/4995 for more details.

If a user is performing a blit to resolve a multisample color buffer
into a single attachment, ANGLE can use subpass resolve attachments to
resolve directly into the destination buffer as part of the render pass.
This allows the data to remain in tiler memory and reduce the extra
bandwidth required to write the multisampled data back to perform the
copy.

This work also requires restoring/reopening a render pass if it has been
finished already, assuming the finished render pass was started and for
the framebuffer that is the source for the blit command. Other objects
that were created when the render pass was started need to be updated as
well, such as the source FramebufferVk's resolve attachment, the
CommandBufferHelper's vk::Framebuffer and vk::RenderPassDesc, etc.

While this is better than performing vkCmdResolveImage(), there is still
another major part of optimizing MSAA using resolve attachments not
implemented here: discarding the multisampled image rather than writing
it to GMEM, which requires the user to invalidate the read FBO after the
blit.

This CL was verified with AGI to make sure there are no explicit blits
to resolve the multiple sampled image.

Re-land fixes the crash when drawing with no bound Program executable.

Currently we track feedback loops by counting the times a Texture is
bound as a sampler or image in a particular context. This is a bit
tricky because Texture bindings change frequently. Relative to the
number of times we need to check for a feedback loop this causes excess
overhead.

Usually Framebuffers have a low number of Textures bound (in many cases
just 1). And Textures aren't usually bound to many different FBOs. So
instead of counting the number of times a Texture is bound as a sampler
or image we will track the Framebuffers that the Texture is bound to.

This CL adds a small vector class to gl::Texture which tracks all the
Framebufer Serials of its bound Framebuffers. We can use this set to
quickly check if there's any potential feedback loop between the a FBO
and this Texture.

We also update the feedback loop check to use this new method. We will
be able to remove the old counting method when we switch the Vulkan
feedback loop handling to use the new tracking in this CL.

- In volk.c, using vkGetInstanceProcAddr and vkGetDeviceProcAddr

- In vk_mem_alloc.h, included from vk_mem_alloc_wrapper.cpp,
  GetAllocationCallbacks() causes a "unrelated cast" error

This cl silences all 3 cfi errors.

This generalizes the read tracking into read/write. Knowing the write
access can let us determine if we can switch a RenderPass to a read-
only mode. And switching to read-only will let us combine some
RenderPasses in Manhattan.

Currently we track feedback loops by counting the times a Texture is
bound as a sampler or image in a particular context. This is a bit
tricky because Texture bindings change frequently. Relative to the
number of times we need to check for a feedback loop this causes excess
overhead.

Usually Framebuffers have a low number of Textures bound (in many cases
just 1). And Textures aren't usually bound to many different FBOs. So
instead of counting the number of times a Texture is bound as a sampler
or image we will track the Framebuffers that the Texture is bound to.

This CL adds a small vector class to gl::Texture which tracks all the
Framebufer Serials of its bound Framebuffers. We can use this set to
quickly check if there's any potential feedback loop between the a FBO
and this Texture.

We also update the feedback loop check to use this new method. We will
be able to remove the old counting method when we switch the Vulkan
feedback loop handling to use the new tracking in this CL.

Because FBOs are unique to a Context, a Texture could be bound to two
different FBOs with the same ID. In this CL we introduce a new Serial
for the FBO which is unique to an EGL Share Group. This way we can
ensure we don't make the wrong call when a Texture is referenced by a
Framebuffer. It also replaces the old FB serial which was again only
unique to a particular Context.
