GL spec requires user culling, then clipping then face culling.
llvmpipe was doing clipping then user culling then face culling.
Fix the ordering by adding a new user_cull stage that does the user
culling
Fixes piglit clip_cull-4.shader_test

This is the bulk of the llvm shader builders and tessellation
execution code.
TCS uses a coroutine launcher like compute shaders to handle
barriers. It executes 4-wide with one input vertex per lane.
Tessellation happens before the TES is run.
TES is just a 4-wide launcher, one per primitive is executed,
with one lane per tessellation coordinate input.

This adds the same tessellator code that swr uses, swr should
move to using this copy, unfortunately that wasn't trivial on my first
look.
The p_tessellator wrapper wraps it in a form that is a useful interface
for draw.

When os_memory_debug.h was promoted to src/util, this source-file on
which it depends on when the debug-flag is set on windows was left
out. So let's move this also.
It doesn't seem there's any way of triggering this issue right now, but
it seems better to correct this to avoid this from biting us in the ass
in the future.

Right now there are two copies of mm:
* mesa/main/mm.[ch]
* gallium/auxiliary/util/u_mm.[ch]
At some point they splitted, and from the commit message it was not
clear why it was not possible to have only one copy at a common place.
Taking into account that was several years ago, Im assuming that it
was not possible then.
This change would allow to have one copy of the same code, and also
being able to use that code out of mesa/main or gallium, if needed.
This commit moves u_mm and removes mm, as u_mm has slightly more
changes.

To make PIPE_FORMATs usable from non-gallium parts of Mesa, I want to
move their helpers out of gallium. Since u_format used
util_copy_rect(), I moved that in there, too.
I've put it in a separate directory in util/ because it's a big chunk
of related code, and it's not clear to me whether we might want it as
a separate library from libmesa_util at some point.

This is (much) faster than using the util fallback.
(Note that there's two methods here, one would use a cache, similar to
the existing code (although the cache was disabled), except the block
decode is done with jit code, the other directly decodes the required
pixels. For now don't use the cache (being direct-mapped is suboptimal,
but it's difficult to come up with something better which doesn't have
too much overhead.)

In order to pull u_debug into src/util we need to break the generically

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.

One of the pains of implementing a gallium driver is filling in a million
pipe caps you don't know about yet when you're just starting out. One of
the pains of working on gallium is copy-and-pasting your new PIPE_CAP into
each driver. We can fix both of these by having each driver call into the
default helper from their default case, so that both sides can ignore each
other until they need to.
v2: fix i915g build, revert swr change to avoid breaking scons build

Add a new helper that drivers can use to emulate various things that
need special handling in particular in transfer_map:
1) z32_s8x24.. gl/gallium treats this as a single buffer with depth
and stencil interleaved but hardware frequently treats this as
separate z32 and s8 buffers. Special pack/unpack handling is
needed in transfer_map/unmap to pack/unpack the exposed buffer
2) fake RGTC.. GPUs designed with GLES in mind, but which can other-
wise do GL3, if native RGTC is not supported it can be emulated
by converting to uncompressed internally, but needs pack/unpack
in transfer_map/unmap
3) MSAA resolves in the transfer_map() case
v2: add MSAA resolve based on Eric's "gallium: Add helpers for MSAA
resolves in pipe_transfer_map()/unmap()." patch; avoid wrapping
pipe_resource, to make it possible for drivers to use both this
and threaded_context.
