mesa,st/mesa: add a fast path for non-static VAOs

Drivers need a separate codepath for this.

This increases performance by 7% with glthread and the game "torcs".

The reason is that glthread uploads vertices and sets vertex buffers
every draw call, so the overhead is very noticable. glthread doesn't
hide the overhead, because the driver thread is the busiest thread.

gallivm: fix half to float conversions with llvm 11

LLVM 11 removes the intrinsic for half to float conversion, so use the fpext
function instead. This function actually works now with half to float, albeit
a quick experiment showed at least the x86 backend cannot lower it itself if
the cpu doesn't support it natively and tries to call external library, which
crashes (and would be very slow anyway as it would be lowered to scalar code),
so for now only use it where we previously used the f16c intrinsic.
