This makes basic built-in functions work in GLSL 1.50. It supports
everything except the new Geometry Shader functions.
The new 150.glsl file is 140.glsl plus ARB_texture_multisample.glsl;
150.frag is identical to 140.frag except for the #version bump.

Commit 33599433c7 began setting the texture swizzle mode to XYZ1 for
RED, RG, and RGB textures in order to force alpha to 1.0 in case we
actually stored the texture as RGBA.
This had a unforseen performance implication: the shader precompile
assumes that the texture swizzle mode will be XYZW for non-shadow
sampler types. By setting it to XYZ1, this means every shader used with
a RED, RG, or RGB texture has to be recompiled. This is a very common
case.
Unfortunately, there's no way to improve the precompile, since RGBA
textures still need XYZW, and there's no way to know by looking at
the shader source what texture formats might be used.
However, we only need to smash alpha to 1.0 if the texture's memory
format actually has alpha bits. If not, the sampler already returns 1.0
for us without any special swizzling. XRGB8888, for example, is a very
common case where this occurs.
This partially fixes a performance regression since commit 33599433c7.
More work is required to fully fix it in all cases. This at least helps
Warsow.

With the old context creation mechanism, an application asked the GL to
give it a context. Failing to produce a context was a fatal error.
Now, with GLX_ARB_create_context, the application can request a specific
version. If it's higher than the maximum version we support, context
creation will fail. But this is a normal error that applications
recover from.
In particular, the new glxinfo tries to create OpenGL 4.3, 4.2, 4.1,
4.0, 3.3, and 3.2 contexts before finally succeeding at creating a 3.1
context. This led to it printing the following message 6 times:
"brwCreateContext: failed to init intel context"
There's no need to alarm users (and developers) with such a message.

On an INTEL_DEBUG=perf piglit run on IVB, reduces the instances of "HW
workaround: blit" (the printouts from the misaligned-depth workaround
blits) from 725 to 675.
It doesn't totally eliminate the workaround blit, because we still have
problems with Y offsets that we can't fix (since texturing can only align
miplevels up to 2 or 4, not 8).
No regressions on piglit/es3conform on IVB.

Previous to this patch, when using fixed function fragment shading,
bit VARYING_BIT_POS of brw_wm_prog_key::proj_attrib_mask was being set
differently during precompiles and normal usage. During precompiles
it was being set only if the fragment shader reads from window
position (which it never does), so it was always being set to 0.
During normal usage it was being set if the vertex shader writes to
all 4 components of gl_Position (which it usually does), so it was
usually being set to 1. As a result, we were almost always doing an
extra recompile for the fixed function fragment shader.
The recompile was totally unnecessary, though, because
brw_wm_prog_key::proj_attrib_mask is only consulted for
fs_visitor::emit_general_interpolation(), which isn't used for
VARYING_SLOT_POS.
This patch avoids the unnecessary recompile by always setting bit
VARYING_BIT_POS of brw_wm_prog_key::proj_attrib_mask to 1.

Previously, right after calling _mesa_glsl_link_shader(), the fixed
function fragment shader code made several calls with the ostensible
purpose of setting up uniforms for the fragment shader it just
created.
These calls are unnecessary, since _mesa_glsl_link_shader() calls
driver->LinkShader(), which takes care of calling these functions (or
their equivalent). Also, they are dangerous to call after
_mesa_glsl_link_shader() has returned, because on back-ends such as
i965 which do precompilation, _mesa_glsl_link_shader() may have
already cached pointers to the existing uniform structures; attempting
to set up the uniforms again invalidates those cached pointers.
It was only by sheer coincidence that this wasn't manifesting itself
as a bug. It turns out that i965's precompile mechanism was always
setting bit 0 of brw_wm_prog_key::proj_attrib_mask to 0 for fixed
function fragment shaders, but during normal usage this bit usually
gets set to 1. As a result, the precompiled shader (with its invalid
uniform pointers) was not being used.
I'm about to introduce some changes that cause bit 0 of
proj_attrib_mask to be set consistently between precompilation and
normal usage, so to avoid regressions I need to get rid of the
dangerous duplicate uniform setup code first.

Since apps typically begin rendering with a call to glClear(), it is
likely that when brw_workaround_depthstencil_alignment() moves a
miplevel to a temporary buffer, it can avoid doing a blit, since the
contents of the miplevel are about to be erased.
This patch adds the necessary plumbing to determine when
brw_workaround_depthstencil_alignment() is being called as a
consequence of glClear(), and avoids the unnecessary blit when it is
safe to do so.

If we're in some conditional or loop we must not return, or the code
after the condition is never executed.
(v2): And, we also can't just continue as nothing happened, since the
mask update code would later check if we actually have a mask, so we
need to remember that there was a return in main where we didn't exit
(to illustrate this, a ret in a if clause would cause a mask update
which is still ok as we're in a conditional, but after the endif the
mask update code would drop the mask hence bringing execution back to
pixels which should have their execution mask set to zero by the ret).
Thanks to Christoph Bumiller for figuring this out.
