_mesa_choose_tex_format (texformat.c) tries I8_SNORM, L8_SNORM, and
either L8A8_SNORM or A8L8_SNORM, none of which are supported by our
driver. Failing that, it falls back to RGBX for luminance, and RGBA
intensity and luminance alpha. So, we need to use swizzle overrrides
to obtain the correct values.
Fixes Piglit's EXT_texture_snorm/fbo-blending-formats and
fbo-clear-formats.

CMP.Z doesn't work on Gen4-5 because the boolean isn't guaranteed to be
0 or 0xFFFFFFFF - only the low bit is defined.
We can call emit_bool_to_cond_code to generate the condition in f0.0;
the last instruction will generate the flag value. We can patch it to
use f0.1, and negate the condition.
Fixes discard tests on Gen4-5.

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.

and enable the code to build with MSVC2013 soon after.

This fixes a dEQP test failure. In the test,
glCompressedTexSubImage2D was called with target = 0 and failed to throw
INVALID ENUM. This failure was caused by _mesa_get_current_tex_object(ctx,
target) being called before the target checking. To remedy this, target
checking was made into its own function and called prior to
_mesa_get_current_tex_object.

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.

A layered PBO image is now interpreted as a single tall 2D image so
the z argument in _mesa_meta_bind_fbo_image is ignored. Therefore this
was just redundantly rebinding the same image repeatedly.

For 32-bit builds, floating point operations use x86 FPU registers,
not SSE registers. If we're actually storing an integer in a float
variable, the value might get modified when written to memory. This
patch changes the VBO code to use the fi_type (float/int union) to
store/copy vertex attributes.
Also, this can improve performance on x86 because moving floats with
integer registers instead of FP registers is faster.
Neil Roberts review:
- include changes on all places that are storing attribute values.
- check with and without -O3 compiler flag.
Brian Paul review:
- use fi_type type instead gl_constant_value type
- fix a bunch of nit-picks.
- fix compiler warnings
