ir_to_mesa: Emit warnings instead of errors for IR that can't be lowered
Rely on the driver to do the right thing. This probably means falling
back to software. Page 88 of the OpenGL 2.1 spec specifically says:
"A shader should not fail to compile, and a program object should
not fail to link due to lack of instruction space or lack of
temporary variables. Implementations should ensure that all valid
shaders and program objects may be successfully compiled, linked
and executed."
There is no provision for saying "No" to a valid shader that is
difficult for the hardware to handle, so stop doing that.
On i915 this causes a large number of piglit tests to change from FAIL
to WARN. The warning is because the driver still emits messages to
stderr like "i915_program_error: Unsupported opcode: BGNLOOP".
It also fixes ES2 conformance CorrectFull_frag and CorrectParse1_frag
on i915 (and probably other hardware that can't handle loops).

-------
In ast_function_expression::hir(), parameter_lists_match() checks if the
function call's actual parameter list matches the signature's parameter
list, where the match may require implicit conversion of some arguments.
To check if an implicit conversion exists between individual arguments,
type_compare() is used.
Problems
--------
type_compare() allowed the following illegal implicit conversions:
bool -> float
bvecN -> vecN
int -> uint
ivecN -> uvecN
uint -> int
uvecN -> ivecN
Change
------
type_compare() is buggy, so replace it with glsl_type::can_be_implicitly_converted_to().

glsl: Correctly return progress from lower_variable_index_to_cond_assign
lower_variable_index_to_cond_assign runs until it can't make any more
progress. It then returns the result of the last pass which will
always be false. This caused the lowering loop in
_mesa_ir_link_shader to end before doing one last round of
lower_if_to_cond_assign. This caused several if-statements (resulting
from lower_variable_index_to_cond_assign) to be left in the IR.
In addition to this change, lower_variable_index_to_cond_assign should
take a flag indicating whether or not it should even generate
if-statements. This is easily controlled by
switch_generator::linear_sequence_max_length. This would generate
much better code on architectures without any flow contol.

Furthermore, since I developed TXD support before Eric's patch, I
neglected to add it to the gradient handling when I rebased.
Neglecting to set this causes the visitor to use this->result as storage

resulted in the same register being used to store several different

glsl: Treat ir_dereference_array of non-var as a constant for lowering
Previously the code would just look at deref->array->type to see if it
was a constant. This isn't good enough because deref->array might be
another ir_dereference_array... of a constant. As a result,
deref->array->type wouldn't be a constant, but
deref->variable_referenced() would return NULL. The unchecked NULL
pointer would shortly lead to a segfault.
Instead just look at the return of deref->variable_referenced(). If
it's NULL, assume that either a constant or some other form of
anonymous temporary storage is being dereferenced.
This is a bit hinkey because most drivers treat constant arrays as
uniforms, but the lowering pass treats them as temporaries. This
keeps the behavior of the old code, so this change isn't making things
worse.

Due to the way it tracked whether the array was being assigned, it

code fixes that by tracking l-values and r-values differently. The
index is also replaced by cloning the IR and replacing the index
