anv: Emit pushed UBO bounds checking code in the back-end compiler

This commit fixes performance regressions introduced by e03f9652801ad7
in which we started bounds checking our push constants.  This added a
LOT of shader code to shaders which use the robustBufferAccess feature
and led to substantial spilling.  The checking we just added to the FS
back-end is far more efficient for two reasons:

 1. It can be done at a whole register granularity rather than per-
    scalar and so we emit one SIMD8 SEL per 32B GRF rather than one
    SIMD16 SEL (executed as two SELs) for each component loaded.

 2. Because we do it with NoMask instructions, we can do it on whole
    pushed GRFs without splatting them out to SIMD8 or SIME16 values.
    This means that robust buffer access no longer explodes our register
    pressure for no good reason.

As a tiny side-benefit, we're now using can use AND instead of SEL which
means no need for the flag and better scheduling.

Vulkan pipeline database results on ICL:

    Instructions in all programs: 293586059 -> 238009118 (-18.9%)

is painfully slow.

Sadly no radeon winsys implementation, as I don't know a suitable
kernel driver operation.

Hit this  in vaGetImage with an image imported from minigbm (which
we are switching to allocate WC for SCANOUT images).

CI: Disable Windows/VS2019 builds

An update seems to have poisoned gitlab-runner, and it can no longer
resolve DNS even though the host system can.

Disable this until we can figure out what's going on.

meson: Make shared-llvm into a tri-state boolean

Choosing LLVM's link mode is legitimate on UNIX systems, but only static
actually really works under Windows.

Give shared-llvm a default 'auto' mode which will pick the previous
default of true (shared) on UNIX systems, but newly defaulting to false
(static) on Windows.

tu: Align GMEM resolve blit scissor

Even though we normally use the CP_BLIT path with resolves that aren't
aligned, there's a special case when we're resolving the entire image
and there's enough padding so that we can still use CP_EVENT_WRITE::BLIT
when the render area isn't aligned. The hardware seems to not like
unaligned scissors when not clearing, and sometimes hangs rather than
silently round the scissor. This causes hangs in e.g.
dEQP-VK.glsl.derivate.dfdx.texture.msaa4.float_highp.

There was some concern that the CP_BLIT path might use this scissor
also, but I confirmed that this isn't the case by setting it to 0 before
resolving and then noting that CP_BLIT still works (but CP_EVENT_WRITE
doesn't). Furthermore, this is actually impossible because of how the 2D
engine is set up: it gets its own pair of register banks, which can be
switched independently of the 3D register banks, so that 2D events
(CP_BLIT) normally aren't synchronized relative to 3D events
(CP_EVENT_WRITE, CP_DRAW_*, and CP_EXEC_CS) and therefore they can't
share any registers except for non-pipelined registers like RB_CCU_CNTL
that don't use the register bank mechanism at all.
