We have competent lowering in NIR already available.

Drivers exposing CAP_DOUBLES but not SHADER_CAP_DROUND:
- d3d12 (NIR lowers ~0 if the underlying impl doesn't do floats)
- svga (Now sets the NIR lowering options)
- softpipe (Doesn't do GL4 so you can't use doubles anyway)
- llvmpipe (Lowers dround_even in NIR and passees the rest through
            successfully)
- zink (NIR lowers ~0 if the underlying impl doesn't do floats,
        otherwise passes things through successfully, except needed
        dround_even lowering to avoid lavapipe regression with
        native doubles)
- r600 (sets NIR rounding lowering flags, and lowers all fsign)

b1b0ebba1e glsl: Remove int64 div/mod lowering. 
Most drivers that can expose GL4 were claiming the cap anyway (llvmpipe,
softpipe, zink, iris, nvc0, radeonsi, r600, freedreno, d3d12), and just
doing lowering in NIR if nessary.

crocus was only claiming the cap for gen8, but the backend compiler
enables NIR lowering regardless.

svga is the only other GL4 driver that didn't set it, and we can just set
the NIR lowering flag.

6b2fa965c6 gallium: Remove PIPE_CAP_RGB_OVERRIDE_DST_ALPHA_BLEND 
Since the mesa state tracker can promote RGB texture formats
to RGBA texture formats (among other formats) without exposing
any of that information to a driver, it is more desirable to
have the behaviour of `PIPE_CAP_RGB_OVERRIDE_DST_ALPHA_BLEND`
be the default. This avoids rendering bugs where an application
sets `DST_ALPHA` blending on a format where there is no alpha
channel, that has been promoted to a format that actually has an
alpha channel. The driver can instead rely on the common code
in the state tracker to convert the blending parameter to one
that reflects the limitations of the application requested format,
as long as `PIPE_CAP_INDEP_BLEND_FUNC` is supported.

While we're at it, make sure math-blocks are indented into their
opcode-block. While the result might look the same most of the time,
this matters when we have textual explaination following math-blocks,
like we have in a few caess. If we don't indent the math there, we
end up with having to unindent the text following the math-block for it
not to count as a part of the math block, which looks very confusing
when reading the source code.
