nir/algebraic: Remove imprecise flog2 optimizations

While mathematically correct, these two optimizations result in an
expression with substantially lower precision than the original.  For any
positive finite floating-point value, log2(x) is well-defined and finite.
More precisely, it is in the range [-150, 150] so any sum of logarithms
log2(a) + log2(b) is also well-defined and finite as long as a and b are
both positive and finite.  However, if a and b are either very small or
very large, their product may get flushed to infinity or zero causing
log2(a * b) to be nowhere close to log2(a) + log2(b).

This imprecision was causing incorrect rendering in Talos Principal because
part of its HDR rendering process involves doing 8 texture operations,
clamping the result to [0, 65000], taking a dot-product with a constant,
and then taking the log2.  This is done 6 or 8 times and summed to produce
the final result which is written to a red texture.  In cases where you
have a region of the screen that is very dark, it can end up getting a
result value of -inf which is not what is intended.

gallivm: don't use integer min/max sse intrinsics with llvm >= 3.9

Apparently, these are deprecated. There's some AutoUpgrade feature which
is supposed to promote these to cmp/select, which apparently doesn't work
with jit code. It is possible it's not actually even meant to work (see
the bug filed against llvm which couldn't provide an answer neither)
but in any case this is meant to be only temporary unless the intrinsics
are really illegal. So, just use the fallback code (which should be cmp/select,
we're actually doing cmp/sext/trunc/select, but in any case llvm 3.9 manages
to optimize this back to pmin/pmax in the end).

nvc0: don't make use of push hint if there are no non-const user vbos

This makes the check match up what we do on nv50 as well - there's no
point in switching over the push path if everything's in managed
buffers. This can happen when a shader uses a vertex without an enabled
array - we end up passing it a constant attribute.

This also has the effect of "fixing" some flickering in Talos. I have no
idea why. I've stared at the push logic forwards, backwards, and
sideways. By always forcing the push path (which is slow), the
flickering also goes away, but other rendering is still wrong
(specifically draw 383068 as identified in the bug). However by not
switching over to the push path, draw 383068 is correct.

Note that other flickering remains in Talos, like the red/green
walls/floors. This takes care of the shadow flickering though.
