It's disabled due to non-conformance with no configuration knob to turn it
on, and if you care about swrast performance you're on llvmpipe anyway.

In release builds, there should be no change, but in debug builds the
assert will help us catch undefined behavior resulting from using
util_cpu_caps before it is initialized.
With fix for u_half_test for MSVC from Jesse Natalie squashed in.

Currently u_math needs gallium utils for cpu detection. Most of what
u_math uses out of u_cpu_detection is duplicated in src/mesa/x86
(surprise!), so I've just reworked it as much as possible to use the
x86/common_x86_features.h macros instead of the gallium ones. The mesa
implementation is a header only approach, with no external dependencies.
There is one small function that was copied over, as promoting
u_cpu_detection is itself a fairly hefty undertaking, as it depends on
u_debug, and this fixes the bug for now.

Currently we have two sets of functions for bit counts, one in gallium
and one in core mesa. The ones in core mesa are header only in many
cases, since they reduce to "#define _mesa_bitcount popcount", but they
provide a fallback implementation. This is important because 32bit msvc
doesn't have popcountll, just popcount; so when nir (for example)
includes the core mesa header it doesn't (and shouldn't) link with core
mesa. To fix this we'll promote the version out of gallium util, then
replace the core mesa uses with the util version, since nir (and other
non-core mesa users) can and do link with mesautils.
