braodcom/vc5: Fix internal type/bpp for RGB10_A2UI images.

I found that we were getting GPU hangs on most tests rendering to them,
and the simulator was assertion failing.

broadcom/vc5: Try to fix up compressed texture load/store.

We were trying to load/store the logical width/height number of compressed
blocks.  As long as the textures were large, single-level, and the
load/store at (0,0), it kind of worked.

broadcom/vc5: Fix image_h value for CPU-side tiling on miplevels > 1.

Fixes overflow that caused failure in
dEQP-GLES3.functional.texture.filtering.2d.sizes.128x128_linear.

broadcom/vc5: Fix discard_if during control flow.

I want to do the SETMSF.IFA to discard only if execute == 0 and cond, so
our dest of the PUSHZ needs to be nonzero if execute or !cond are nonzero.

Fixes dEQP-GLES3.functional.shaders.discard.dynamic_loop_dynamic.

broadcom/vc5: Disable early Z when the stencil func isn't ALWAYS.

Apparently the other funcs will have observable differences when early Z
is enabled.

Fixes (new) simulator assertion failures in
dEQP-GLES3.functional.rasterizer_discard.basic.clear_depth.

broadcom/vc5: Don't emit component 3/4 F16 TLB writes for float/vec2.

Fixes a simulator assertion failure on
dEQP-GLES3.functional.fragment_out.array.fixed.r8_highp_float.

nir: Add a helper to get the uvec4 type.

broadcom/vc5: Introduce enums for internal depth/type, with V3D prefixes.

broadcom/xml: Fix up safe name confusion with prefixing.

For enums we were doubling the underscore if the value had a numeric first
character of its name (which safe_name() adds an underscore to).  A little
helper function cleans up the other instance of prefixing while also
fixing this.

broadcom/vc5: Turn the decimate mode field into an enum in the XML.

broadcom/vc5: Turn the output image format into an enum.

broadcom/vc5: Turn the CLE XML's memory format into an enum.

broadcom/vc5: Emit flat shade flags for varying components > 24.

This means that with no flatshading we'll emit the single-byte
ZERO_ALL_FLAT_SHADE_FLAGS, and otherwise emit a set of FLAT_SHADE_FLAGS to
get all the bits we need set.

There's a _SET enum in the packet we could use to possibly set entire
ranges of the bitfield without using another packet, but this at least
fixes the conformance failure.

broadcom/vc5: Emit proper flatshading code for glShadeModel(GL_FLAT).

In updating the simulator, behavior changed slightly so that our old code
wasn't getting glxgears's flatshading interpolated right.  Emit flat
shading code just like we would for a normal flat-shaded varying, by
passing a flag in the shader key for glShadeModel(GL_FLAT) state and
customizing the color inputs based on that.

braodcom/vc5: Rely on OVRTMUOUT always being set.

It seems that the HW team has decided that it's the only supported mode,
and it's the mode I actually meant to be using but forgot.  Our table of
return_32_bit should have matched the default non-OVRTMUOUT behavior, so
this change should be invisible.

However, the change revealed that some my return_size checks for swizzling
were a bit confused in the shadow case, so I had to move them to draw time
once we have both the sampler and the view together.

Fixes assertion failures in the updated simulator, where the non-OVRTMUOUT
support has been removed.

broadcom/vc5: Move texture return channel setup into the compiler.

The compiler decides how many LDTMUs we're going to emit, and that must
match the P1 flags.  This brings the return channel counting to a single
place (so all that's passed into the compiler is "how many return channels
you may request from this texture's format), and was a necessary step for
shadow samplers once we stop using OVRTMUOUT=0.

broadcom/vc5: Switch to setting the primitive list format in the RCL.

This means that we get a single copy of it emitted, instead of once at the
start of each tile (though it's still executed once per tile).  Fixes
assertion failures with the updated simulator.

broadcom/vc5: Switch to using the C++ interface for the simulator.

In newer versions they've removed the C interface, so make one here.  This
also isolates the Mesa codebase from the simulator codebase, so we don't
have conflicts over things like "unreachable"

mesa: Add GL_UNSIGNED_INT_2_10_10_10_REV OES read type for BGRX1010102.

As Marek noted, the GL_RGBA + GL_UNSIGNED_INT_2_10_10_10_REV type
combo is also good for readback of BGRX1010102 framebuffers, not
only for BGRA1010102 framebuffers for use with glReadPixels()
under GLES, so add it for the GL_IMPLEMENTATION_COLOR_READ_TYPE_OES
query.

Successfully tested on gallium r600 driver with a (quickly hacked
for RGBA 10 10 10 0) dEQP testcase
dEQP-EGL.functional.wide_color.window_1010102_colorspace_default.
