The code for handling implicit conversions should probably get
refactored, but for now, this is easy.
Fixes piglit test constructor-26.vert.

I'm not sure if this is strictly necessary, but it seems wise.

If the matrix being constructed was larger than the source matrix, it
would overwrite the lower-right part of the matrix with the wrong
values, rather than leaving it as the identity matrix.
For example, constructing a mat4 from a mat2 should only use a writemask
of "xy" when copying from the source, but was using "xyzw".
Fixes the code generated by piglit test constructor-23.vert.

This was triggering even for matrix-from-matrix constructors. It is
perfectly legal to construct a mat3 from a mat2 - the rest will be
filled in by the identity matrix.
Changes piglit test constructor-23.vert from FAIL to PASS, but the
generated code is incorrect.

There are no integer matrix types, so switching on them is silly.

Make two passes over the constructor parameters. Write all of the
constants in a single write, then write the non-constants one at a
time. This causes the fragment shader
varying float g;
void main()
{
gl_FragColor = vec4(0.0, g, 0.0, 1.0);
}
to generate
(function main
(signature void (parameters )
(
(declare (temporary ) vec4 vec_ctor@0x8580058)
(assign (constant bool (1)) (xzw) (var_ref vec_ctor@0x8580058) (constant vec4 (0.000000 0.000000 0.000000 1.000000)) )
(assign (constant bool (1)) (y) (var_ref vec_ctor@0x8580058) (swiz xxxx (var_ref g@0x8580218) ))
(assign (constant bool (1)) (xyzw) (var_ref gl_FragColor@0x84d32a0) (var_ref vec_ctor@0x8580058) )
))
)
instead of
(function main
(signature void (parameters )
(
(declare (temporary ) vec4 vec_ctor@0x8580058)
(assign (constant bool (1)) (x) (var_ref vec_ctor@0x8580058) (constant vec4 (0.000000 0.000000 0.000000 1.000000)) )
(assign (constant bool (1)) (y) (var_ref vec_ctor@0x8580058) (swiz xxxx (var_ref g@0x8580218) ))
(assign (constant bool (1)) (z) (var_ref vec_ctor@0x8580058) (constant vec4 (0.000000 0.000000 0.000000 1.000000)) )
(assign (constant bool (1)) (w) (var_ref vec_ctor@0x8580058) (constant vec4 (0.000000 0.000000 0.000000 1.000000)) )
(assign (constant bool (1)) (xyzw) (var_ref gl_FragColor@0x84d32a0) (var_ref vec_ctor@0x8580058) )
))
)
A similar optimization could be done for matrix constructors, but it
is a little more complicate there.

Completely initialize data that is passed to ir_constant constructor.

This error led to an assertion failure for some constructors of
non-square matrices. It only occured in matrices where the number of
columns was greater than the number of rows. It didn't even always
occur on those.

Previously the in-line matrix and vector constructors would generate
swizzles in the LHS. The code is actually more clear if it just
generates the masked assignments instead of relying on the
ir_assignment constructor to convert the swizzles to write masks.

ir_variable always strdups the incoming name so that it matches the
lifetime of the ir_variable.

Since GLSL permits arrays of structures, we need to store each element
as an ir_constant*, not just ir_constant_data.
Fixes parser tests const-array-01.frag, const-array-03.frag,
const-array-04.frag, const-array-05.frag, though 03 and 04 generate the
wrong code.

This is quite a large patch because breaking it into smaller pieces
would result in the tree being intermitently broken. The big changes
are:
* Add the ir_var_temporary variable mode
* Change the ir_variable constructor to take the mode as a
parameter and correctly specify the mode for all ir_varables.
* Change the linker to not cross validate ir_var_temporary
variables.
* Change the linker to pull all ir_var_temporary variables from
global scope into 'main'.

If they have a return value, this means putting it into a temporary
and making a deref of the temp be the rvalue, since we don't know if
the rvalue will be used or not.

Previously, code like ivec4(mat2(...)) would fail because the compiler
would naively try to convert a mat2 to an imat2...which doesn't exist.
Now, a separate pass breaks such matrices down to their columns, which
can be converted from vec2 to ivec2.
Fixes piglit tests constructor-11.vert, constructor-14.vert,
constructor-15.vert, and CorrectConstFolding2.frag.

This case is already caught by a later check that ensures sufficient
components were provided, based on the type.

_mesa_glsl_parse_state should be the parent for all temporary allocation
done while compiling a shader. glsl_shader should only be used as the
parent for the shader's final IR---the _result_ of compilation.
Since many IR instructions may be added or discarded during optimization
passes, IR should not ever be allocated to glsl_shader directly.
Done via sed -i s/talloc_parent(state)/state/g and s/talloc_parent(st)/st/g.
This also removes a ton of talloc_parent calls, which may help performance.

Now that all scalar, vector, and matrix constructors are emitted
in-line, the parameters to these constructors should not be flattened
to a pile of scalars. Instead, the functions that emit the in-line
constructor bodies can directly write the parameters to the correct
locations in the objects being constructed.
