Initial bits to process initializers in variable declarations
As a result, the following tests pass:
glslparsertest/array3.frag
glslparsertest/CGStandardLibrary.frag
glslparsertest/ConstantConversions.frag
glslparsertest/constructor1.frag
glslparsertest/constructor2.frag
glslparsertest/constructor3.V110.frag
glslparsertest/dataType4.frag
glslparsertest/dataType5.frag
glslparsertest/dataType13.frag
glslparsertest/dataType19.frag
glslparsertest/matrix.V110.frag
glslparsertest/parser7.frag
glslparsertest/swizzle3.frag
The following tests also pass, but it is just by dumb luck. In these
cases the shader fails to compile, but it fails for the wrong reason:
glslparsertest/array6.frag
glslparsertest/comma2.frag
glslparsertest/conditional1.frag
glslparsertest/conditional2.frag
glslparsertest/conditional3.frag
glslparsertest/constFunc.frag
glslparsertest/ParseTest3.frag
glslparsertest/ParseTest4.frag
glslparsertest/varying3.frag
glslparsertest/parser8.frag (also segfaults)
glslparsertest/parser9.frag (also segfaults)
The following tests now fail. As far as I can tell, these are all
cases where the shader was failing to compile, but it was failing for
the wrong reason.
glslparsertest/CorrectMatComma.frag
glslparsertest/CorrectModule.frag
glslparsertest/CorrectSwizzle2.vert
glslparsertest/shaders/glsl-fs-bug25902.frag
Initial implementation of constructor handling code
All of the scalar, vector, and matrix constructors *except* "from
bool" constructors should be handled. Array and structure
constructors are also not yet handled.
Slightly change the representation of numeric types
For numeric types, vector_elements and matrix_columns must be at least
1. Previously matrix_columns was 0 for vectors, and both were 0 for
scalars. This change simplifies things in some places.
Move swizzles out of ir_dereference and into their own class.
Also turn generate_swizzle into a static "create" method of the new
class; we'll want to use it for the IR reader as well.

IR print visitor: print ir_dereference instructions
Also make a slight change to ir_variable. The ir_dereference tracks
the number of nested dereferences. If an ir_variable is visited and
the count is non-zero, just print the name of the variable.
Basically, replace everything different from operator_assign other
than the creation of the rhs value from the lvalue and rvalue with the
contents of operator_assign. Fixes a segfault in
CorrectSwizzle1.frag, and fixes parser10.frag.
Newb GL mistake: matrices in GL are column-major. This means that
vector_elements is the number of rows. Making these changes causes
matrix-08.glsl to pass.
