gallium/util: add util_bitcount64

I'll need this in radeonsi.

v2: use __builtin_popcountll if available

radeonsi: always compile shaders on demand

The first compiled shader is sometimes useless, because the key doesn't match
the key for the draw call where it's used.

radeonsi: remove interp_at_sample from the key, use TGSI_INTERPOLATE_LOC_SAMPLE

st/mesa has the same flag in its shader key, we don't need to do it
in the driver anymore.

Instead, use TGSI_INTERPOLATE_LOC_SAMPLE, which is what st/mesa sets.

radeonsi: don't flush shader caches when building PM4 shader states

This is a wrong place to flush caches to say the least.

I don't think we need to flush the instruction caches if we don't patch
shaders with DMA.

We only support 16 vertex attribs, not 32.

radeonsi: set number of userdata SGPRs of GS copy shader to 4

It only needs the constant buffer with clip planes and read-write resources
for the GS->VS ring and streamout. That's 2 pointers.

ilo: let shaders determine sampler counts

When a shader needs N samplers, we should upload N samplers and not depend on
how many are bound.
