This enables GL_shader_draw_parameters and GL_ARB_indirect_parameters as well
as a properly accelerated implementation of GL_ARB_multi_draw_indirect.
Enabling the feature requires a sufficiently uptodate firmware -- those have
already been released a long time ago, although this does mean that the
feature only works with the amdgpu kernel module, since the radeon module
doesn't have a way to query the firmware version.

Previously we would not print a swizzle on ssa_52 when only its .x
component is used (as seen in the definition of ssa_53):
vec3 ssa_52 = fadd ssa_51, ssa_51
vec1 ssa_53 = flog2 ssa_52
vec1 ssa_54 = flog2 ssa_52.y
vec1 ssa_55 = flog2 ssa_52.z
But this makes the interpretation of the RHS of the definition difficult
to understand and dependent on the size of the LHS. Just print swizzles
when they are not the identity swizzle, so the previous example is now
printed as:
vec3 ssa_52 = fadd ssa_51.xyz, ssa_51.xyz
vec1 ssa_53 = flog2 ssa_52.x
vec1 ssa_54 = flog2 ssa_52.y

OpenGL 4.4 specifies that BlitFramebuffer should perform sRGB encode
and decode like ES 3.x does, but only when GL_FRAMEBUFFER_SRGB is
enabled. This is technically incompatible in certain cases, but is
more consistent across GL, ES, and WebGL, and more flexible.
The NVIDIA 367.35 drivers appear to follow this behavior.

I've never quite understood the purpose of this hack - supposedly,
doing resolves in the sRGB colorspace is slightly more accurate.
Currently, BlitFramebuffer() ignores sRGB encoding and decoding
on OpenGL, although it encodes and decodes in GLES 3.x.
The updated OpenGL 4.4 rules also allow for encoding and decoding
if GL_FRAMEBUFFER_SRGB is enabled, allowing the application to
control what colorspace blits are done in. I don't think this hack
makes any sense in such a world - the application can do what it
wants, and we shouldn't second guess them.
A related Piglit patch, "Make multisample accuracy test set
GL_FRAMEBUFFER_SRGB when resolving." makes the Piglit MSAA accuracy
test explicitly request SRGB encoding/decoding during resolves when
running "srgb" subtests. Without that patch, this commit will regress
those tests, but with it, they should continue to work just fine.

Modern OpenGL BlitFramebuffer require sRGB encode/decode when
GL_FRAMEBUFFER_SRGB is enabled. The blitter can't handle this,
so we need to bail. On Gen4-5, this means falling back to Meta,
which should handle it.
We allow sRGB <-> sRGB blits, as decode then encode ought to be a noop
(other than potential precision loss, which nobody wants anyway).

The multisample rasterization mode is computed based on this field,

are two tables in the SKL PRM that describe how the final multisample mode
is calculated: "Windower (WM) Stage >> Multisampling >> Multisample
ModeState >> Table 1" and the formula for "SF_INT::Multisample
Rasterization Mode".
The "DX Multisample Rasterization Enable" bit changes whether multisample
mode is set to OFF_PIXEL or ON_PATTERN in the samples > 1 case. In the
samples == 1 case, the bit has no effect. Since Vulkan has no concept of
disabling multisampling for samples > 1, we can just set the bit.
