compiler: Save a single copy of the softfp64 shader in the context.
We were recompiling the softfp64 library of functions from GLSL to NIR
every time we compiled a shader that used fp64. Worse, we were ralloc
stealing it to the GL context. This meant that we'd accumulate lots of
copies for the lifetime of the context, which was a big space leak.
Instead, we can simply stash a single copy in the GL context, and use
it for subsequent compiles. Having a single copy should be fine from
a memory context point of view: nir_inline_function_impl already clones
the necessary nir_function_impl's as it inlines.
KHR-GL45.enhanced_layouts.ssb_member_align_non_power_of_2 was previously
OOM'ing a system with 16GB of RAM when using softfp64. Now it finishes

gallium: get rid of PIPE_CAP_SM3
PIPE_CAP_SM3 has always been an odd one out of all our caps. While most
other caps are fine-grained and single-purpose, this cap encode several
features in one. And since OpenGL cares more about single features, it'd
be nice to get rid of this one.
As it turns, this is now relatively simple. We only really care about
three features using this cap, and those already got their own caps. So
we can remove it, and make sure all current drivers just give the same
response to all of them.
The only place we *really* care about SM3 is in nine, and there we can
instead just re-construct the information based on the finer-grained
caps. This avoids DX9 semantics from needlessly leaking into all of the
drivers, most of who doesn't care a whole lot about DX9 specifically.

panfrost: Handle "blend disabled" blend shaders
Normally, disabled blend can definitely be fixed-function'd away, but
if a blend shader is used merely for format conversion rather than
blending, this code path can be nevertheless hit.

panfrost/midgard: Implement integer downsize ops
Oh, dear. No turning back now.
We begin implementing non-32-bit types, using downsizing integer type
conversions as the initial instructions. We implement them naively as
type-converting moves; substantially more efficient operation is
possible by copypropping the type conversion modifier, but this
optimization is not implemented here.
Size converting modifiers on Midgard allow an instruction to write to a
destination 1/2 the size, or to read from a source 1/2 the size. If we
need an extreme conversion (32-bit to 8-bit, for instance), multiple
type converting ops are chained together, which here is handled via an
algebraic pass.
