There are still some edge cases which result in a neighbor-loop. Which
needs to be fixed, but this hack at least makes deqp tests finish.

Fixes a bunch of flat-varying fail on a4xx (where we need to use ldlv to
read the un-interpolated varying).

Since we cannot mov into a predicate register, the frontend uses a
'cmps.s p0.x, cond, 0' as a stand-in for mov to p0.x. It does this
since it has no way to know that the source cond instruction (ie.
for a kill, br, etc) will only be used to write the predicate reg.
Detect this, and re-write the instruction writing p0.x to skip the
original cmps.[sfu]. (It is done like this, rather than re-writing
the dest of the first cmps.[sfu] in case the first cmps.[sfu]
actually has other users.)

We used to use sse roundps intrinsic directly, but switched to use the llvm
intrinsics for rounding with e4f01da15d.
However, llvm semantics follows standard math lib round function which is
specced to do roundNearestAwayFromZero but we really want roundNearestEven
(moreoever, using round generates atrocious code since the cpu can't do it
directly and it results in scalar calls to libm __roundf).
So, use llvm.nearbyint instead, which does exactly the right thing, and even
has the advantage of being available with llvm 3.3 too. (I've verified it
actually generates a roundps instruction with llvm 3.3.)

This fixes a compile error while building Nouveau with C++11 enabled (and
glibc >= 2.23). This happens if SWR is enabled, as it forces C++11.

libasan is never linked to shared objects (which doesn't go well with
-z,defs). It must either be linked to the main executable, or (more
practically for OpenGL drivers) be pre-loaded via LD_PRELOAD.
Otherwise works.
I didn't find anything with llvmpipe. I suspect the fact that the
JIT compiled code isn't instrumented means there are lots of errors it
can't catch.
But for non-JIT drivers, the Address/Leak Sanitizers seem like a faster
alternative to Valgrind.
Usage (Ubuntu 15.10):
scons asan=1 libgl-xlib
export LD_LIBRARY_PATH=$PWD/build/linux-x86_64-debug/gallium/targets/libgl-xlib
LD_PRELOAD=libasan.so.2 any-opengl-application
