anv/pipeline: Add a mem_ctx parameter to anv_pipeline_compile

i965: Store image_param in brw_context instead of prog_data

This burns an extra 10k of memory or so in the case where you don't have
any images.  However, if you have several shaders which use images, this

intel: Rewrite the world of push/pull params

This moves us away to the array of pointers model and onto a model where
each param is represented by a generic uint32_t handle.  We reserve 2^16
of these handles for builtins that get generated by somewhere inside the
compiler and have well-defined meanings.  Generic params have handles
whose meanings are defined by the driver.

The primary downside to this new approach is that it moves a little bit
of the work that we would normally do at compile time to draw time.  On
my laptop this hurts OglBatch6 by no more than 1% and doesn't seem to
have any measurable affect on OglBatch7.  So, while this may come back
to bite us, it doesn't look too bad.

i965: Ignore GL_SKIP_DECODE_EXT for textures accessed via texelFetch().

The GL_EXT_texture_sRGB_decode spec says:

"The conversion of sRGB color space components to linear color space is
 always performed if the texel lookup function is one of the texelFetch
 builtin functions.

 Otherwise, if the texel lookup function is one of the texture builtin
 functions or one of the texture gather functions, the conversion of sRGB
 color space components to linear color space is controlled by the
 TEXTURE_SRGB_DECODE_EXT parameter.

 If the TEXTURE_SRGB_DECODE_EXT parameter is DECODE_EXT, the conversion
 of sRGB color space components to linear color space is performed.

 If the TEXTURE_SRGB_DECODE_EXT parameter is SKIP_DECODE_EXT, the value
 is returned without decoding. However, if the texture is also accessed
 with a texelFetch function, then the result of texture builtin functions
 and/or texture gather functions may be returned with decoding or without

This patch makes i965 force sRGB decoding for any textures accessed via
texelFetch().  If textures are accessed via texelFetch() and a regular
texture access function, this will affect the other ones too - which is
fine - it's undefined according to the last paragraph quoted.

We could make both work, but we'd have to emit multiple SURFACE_STATEs,

    If an error is not generated, such commands will have undefined

i965: Fix output register sizes when multiple variables share a slot.

ARB_enhanced_layouts allows multiple output variables to share the same
location - and these variables may not have the same sizes.  For
example, consider these output variables:

   // consume X/Y/Z components of 6 vectors
   layout(location = 0) out vec3 a[6];

   // consumes W component of the first vector
   layout(location = 0, component = 3) out float b;

Looking at the first declaration, we see that VARYING_SLOT_VAR0 needs 24
components worth of space (vec3 padded out to a vec4, 4 * 6 = 24).  But
looking at the second declaration, we would think that VARYING_SLOT_VAR0
needs only 4 components of space (a single float padded out to a vec4).

nir_setup_outputs() only considered the space requirements of the first
declaration it happened to see, so if 'float b' came first, it would
underallocate the output register space, causing brw_fs_validator.cpp
to assert fail about inst->dst.offset exceeding the register size.

Fixes Piglit's tests/spec/arb_enhanced_layouts/execution/component-layout/
vs-to-fs-array-interleave-single-location.shader_test.
