This adds the following template options:
- add an option to fill TC set_vertex_buffers from st_update_array directly
(always true without u_vbuf, so always used with radeonsi)
- add an option saying that there are no zero-stride attribs
- add an option saying that there are no user buffers
(always true with glthread, so always used with radeonsi)
- add an option saying that there is an identity mapping between vertex
buffers and vertex attribs
I have specifically chosen those options because they improve performance.
I also had other options that didn't, like unrolling the setup_arrays loop.
This adds a total of 42 variants of st_update_array_templ for various cases.
Usually only a few of them are used in practice.
Overhead of st_prepare_draw in VP2020/Catia:
Before: 8.5% of CPU used
After: 6.13% of CPU used
That's 2.37% improvement. Since there are 4 threads using the CPU and
the percentage includes all threads in the system, the improvement for
the GL thread is about 8% (roughly 2.17% * 4; each thread at 25% of global
utilization means 100% utilization in 4 cores).

Widens the given bit mask by a multiplier, meaning that it will
replicate each bit by that amount.
For example: 0b101 widened by 2 will become: 0b110011
This is typically used in shader I/O to transform a 64-bit
writemask to a 32-bit writemask.
Moving this function here because it is used in multiple places.

While the documentation for _BitScanReverse64 on MSDN says that it's
available on ARM, this isn't true. It's only available on ARM64. So
let's match reality.

bitcount is free from the pipe header dependencies that make u_math.h hard
to include by non-gallium specific code, so move it to bitscan.h. bitscan.h
is included by u_math.h so existing references will continue working.

Otherwise we'll get errors such as
error: conflicting types for ‘ffs’
error: conflicting types for ‘ffsll’
We might want to improve the heuristics and provide a definition only
when a native one is missing. We can address that at a later stage.
