The main objective of this change is to enable Linux developers to use
more of C99 throughout Mesa, with confidence that the portions that need
to be built with MSVC -- and only those portions --, stay portable.
This is achieved by using the appropriate -Werror= options only on the
places they need to be used.
Unfortunately we still need MSVC 2008 on a few portions of the code
(namely llvmpipe and its dependencies). I hope to eventually eliminate
this so that we can use C99 everywhere, but there are technical/logistic
challenges (specifically, newer Windows SDKs no longer bundle MSVC,
instead require a full installation of Visual Studio, and that has
hindered adoption of newer MSVC versions on our build processes.)
Thankfully we have more directy control over our OpenGL driver, which is
why we're now able to migrate to MSVC 2013 for most of the tree.

MSVC 2008 (shipped with Windows SDK 7.0.7600) is the oldest we
need to support. At least on llvmpipe, gallium/auxiliary, and util
modules. For the remaining modules (particular all OpenGL specific
code) can be built with MSVC 2013.

The alternative would be to include math.h in c99_compat.h but that
seems heavy-handed.
This patch also replaces INLINE with inline in the c99 math function
wrappers.

... and util_le{16,32}_to_cpu. I think I've used the right ones for
describing the actual operation performed (even though they're both just
"byte-swap this if I'm on big-endian").
The Linux Kernel has typedefs __le32/__be32 and friends that static
analysis tools can use to check that byte-orderings are correct. It
might be interesting to apply that here as well.

It introduces references to gallium util/ symbols which means we don't get

These act like flt32 except they take up two slots, and you
can only add 2 x flt64 constants in one slot.
The main reason they are different is we don't want to match half a flt64
constants against a flt32 constant in the matching code, we need to make
sure we treat both parts of the flt64 as an single structure.

This patch adds support for a set of double opcodes
to TGSI. It is an update of work done originally
by Michal Krol on the gallium-double-opcodes branch.
The opcodes have a hint where they came from in the
header file.
v2: add unsigned/int <-> double
v2.1: update docs.
v3: add DRSQ (Glenn), fix review comments (Glenn).
v4: drop DDIV
v4.1: cleanups, fix some docs bugs, (Ilia)
rework store_dest and fetch_source fns. (Ilia)
4.2: fixup float comparisons (Ilia)
This is based on code by Michael Krol <michal@vmware.com>
Roland and Glenn also reviewed earlier versions.

With commit c39dbfdd0f7(auxiliary/vl: bring back the VL code for the dri

ended up trying to compile the dri2 specific code on platform which lack
it - Cygwin for example.

We can eventually generalize this to other OSes, but for that we must
restrict the function to be called from the current thread. See also

With commit c642e87d9f4(auxiliary/vl: rework the build of the VL code)
we split out the VL code into a separate static library that was meant
to be used by the VL targets alone - va, vdpau, xvmc.
The commit failed to consider the way we handle vdpau-gl interop and
broke it. Bring back the functionality by keeping the vl <> vl_stub
separation as requrested by Christian.
v2: Update the omx target as well. Update mesa-stable email address.

This expects (0,0,0,0), though it can be changed to something else or allow
more than one set of values to be considered correct.
This is currently the radeonsi behavior.

As ffsll doesn't exist in MSVC yet, and u_bit_scan64 is only used by
radeonsi which is never built with MSVC.
This is just a stop-gap fix to unbreak MSVC build until we refactor these
mathematical portability wrappers into src/util.
Trivial.
E.g. r600g can use slot 17, which is outside of the API range.

NOTE IN[] and OUT[] don't need (have?) ArrayID's.. and TEMP[] can
optionally have them. So we implicitly assume that ArrayID==0 always
exists for each file. This is why array_max[file] is never less than
zero.
You can tell from indirect_files(_read/written) if the legacy array-
id zero was actually used.

At least temporarily, I need to fallback to old compiler still for
relative dest (for freedreno), but I can do relative src temp. Only
a temporary situation, but seems easy/reasonable for tgsi-scan to
track this.

The "normal" detection (querying clflush size) already made sure it is
non-zero, however another method did not. This lead to crashes if this
value happened to be zero (apparently can happen in virtualized environments
at least).
