Also changes the print visitor to not emit extraneous parenthesis.

350bd70348 ir_reader: Fix reading of array deferences and correct error messages. 
Previously, the syntax was (array_ref <variable name> <index>), but the
subject is now a general rvalue (not a name).  In particular, it might
be a (var_ref ...).

Also, remove "expected ... or (swiz)" from error messages; swiz is not
allowed inside a var_ref.

a9159f9e87 Fix setting the maximum accessed array element 
Array dereferences now point to variable dereferences instead of
pointing directly to variables.  This necessitated some changes to the
way the variable is accessed when setting the maximum index array element.

classes.

f3a002b503 Refactor ir_dereference support for ir_hierarchical_visitor 
Move the accept method for hierarchical visitors from ir_dereference
to the derived classes.  This was mostly straight-forward, but I
suspect that ir_dead_code_local may be broken now.

70fe8b6663 Begin refactoring ir_dereference 
Create separate subclasses of ir_dereference for variable, array, and
record dereferences.  As a side effect, array and record dereferences
no longer point to ir_variable objects directly.  Instead they each
point to an ir_dereference_variable object.

This is the first of several steps in the refactoring process.  The
intention is that ir_dereference will eventually become an abstract
base class.

77dd4f3536 Reimplement has_call_callback using ir_hierarchical_vistor

soon as the first call is found.

current uses of ir_visitor.

that was implemented first.

4cfbad9e4d exec_list: Add foreach_list_typed and foreach_list_typed_const 
These variations are parameterized by the type of the nodes in the
list.  This enables skipping the explicit usage of exec_node_data in
the loop body.

4f9d72fa9e Loop bodies, then-statements, and else-statements are not lists 
The statement making up a loop body, a then-statement, or an
else-statement are single nodes.  If the statement is a block, the
single node will be an ast_compound_statement.  There is no need to
loop at the top level when processing these statements.

3521f0bdd5 Store AST function call parameters in expressions 
Previously the list of function call parameters was stored as a
circular list in ast_expression::subexpressions[1].  They are now
stored as a regular list in ast_expression::expressions.

6255a1f4c6 ir_dead_code_local: Remove redundant assignments within basic blocks. 
This cleans up a bunch of junk code in some of the GLSL parser tests,
and could potentially help real-world too (particularly after copy
propagation has happened).
