e29a585989 Use ir_variable::clone to copy parameters to the function body 
Several other code movements were also done.  This partitions this
function into two halves.  The first half processes the prototype
part, and the second have processes the actual function definition.
The coming patch series will parition ast_function_definition::hir
into (at least) two separate functions.

0ed6125725 Test that const declarations include initializers. 
Fixes dataType6.frag, and also array2.frag for an unexpected but valid
reason.

e0800062da Reject declarations with 'in' or 'out' qualifiers 
'in' and 'out' can only be used in function parameter lists or at
global scope (1.30 and later).  This change enforces this.

previously failing to compile, but they were all failing for the wrong
reasons.

bfb09c2a94 Use call-by-reference for apply_implicit_conversion 
I'm not sure if this is a win or not.  It makes the code in
apply_implicit_conversion more clear, but it obscures the fact that it
may change the pointers.

The following tests now pass:

    glslparsertest/shaders/if1.frag
    glslparsertest/shaders/if2.frag

The following tests that used to pass now fail.  It appears that most
of these fail because ast_nequal and ast_equal are not converted to HIR.

66faec4895 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

affc1413ac 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.
