ac: make use of if/loop build helpers

These helpers insert the basic block in the same order as they
appear in NIR making it easier to follow LLVM IR dumps. The helpers
also insert more useful labels onto the blocks.

TGSI use the line number of the corresponding opcode in the TGSI
dump as the label id, here we use the corresponding block index
from NIR.

draw: fix line stippling with aa lines

In contrast to non-aa, where stippling is based on either dx or dy
(depending on if it's a x or y major line), stippling is based on
actual distance with smooth lines, so adjust for this.

(It looks like there's some minor artifacts with mesa demos
line-sample and stippling, it looks like the line endpoints
aren't quite right with aa + stippling - maybe due to the
integer math in the stipple stage, but I can't quite pinpoint it.)

draw: simplify (and correct) aaline fallback (v2)

The motivation actually was to get rid of the additional tex
instruction, since that requires the draw fallback code to intercept
all sampler / view calls (even if the fallback is never hit).
Basically, the idea is to use coverage of the pixel to calculate
the alpha value, and coverage is simply based on the distance
to the center of the line (in both line direction, which is useful
for wide lines, as well as perpendicular to the line).
This is much closer to what hw supporting this natively actually does.
It also fixes an issue with line width not quite being correct, as
well as endpoints getting stretched too far (in line direction) with
wide lines, which is apparent with mesa demo line-sample.
(For llvmpipe, it would probably make sense to do something like this
directly when drawing lines, since rendering two tris is twice as
expensive as a line, but it would need some changes with state
management.)
Since we're no longer relying on mipmapping to get the alpha value,
we also don't need to draw 3 rects (6 tris), one is sufficient.

There's still issues (as before):
- quite sure it's not correct without half_pixel_center, but can't test
this with GL.
- aaline + line stipple is incorrect (evident with line-sample demo).
Looking at the spec the stipple pattern should actually be based on
distance (not just dx or dy for x/y major lines as without aa).
- outputs (other than pos + the one used for line aa) should be
reinterpolated since we actually increase line length by half a pixel
(but there's no tests which would care).

v2: simplify the math (should be equivalent), don't need immediate
v3: use float versions of atan2,cos,sin, minor cleanups

Given a binary operation #, a scan takes the vector [a0, a1, ..., aN]
and returns the vector [a0, a0 # a1, ..., a0 # a1 # ... # aN] where each
channel contains the combination of all previous channels.  The sequence
of instructions to perform the scan is fairly optimal; a 16-wide scan on
a 32-bit type is only 6 instructions.  The subgroup scan and reduction
operations will be implemented in terms of this.

glsl: Fix memory leak with known glsl_type instances

When looking up known glsl_type instances in the various hash tables, we
end up leaking the key instances used for the lookup, as the glsl_type
constructor allocates memory on the global mem_ctx. This patch changes
glsl_type to manage its own memory, which fixes the leak and also allows
getting rid of the global mem_ctx and its mutex.

v2: remove lambda usage (Tapani)
    (+keep ASSERT_BITFIELD_SIZE, modify dummy ctor to initialize mem_ctx)
