ebefeb2bdd Attach a pointer to variable names in LIR dumping. 
Since variable names are not unique, and we like to make lots of
__retvals and assignment_tmps and a,b,c,d this helps in debugging.

4b6fd39c89 Add a virtual clone() method to ir_instruction. 
This will be used by function inlining, the linker, and avoiding double
usage of the LHS deref chains in ++, *=, and similar operations.

e46a454305 ir: Give ir_instruction a print visitor helper. 
This avoids spamming each file with includes of ir_print_visitor.h
because someone was doing debugging at some point, and is less typing
when doing debugging.

7d82c765a8 IR print visitor: Just print the name of structures

the structure defintion elsewhere.

405e122a47 ir_print_visitor: Print (constant bool (1)) instead of "true" 
It might be better to simply handle "true" in the reader, but since
booleans normally aren't printed as "true" or "false", we may as well go
for consistency.

1a3a096bf5 ir_print_visitor: print the type of expressions. 
This can be useful for debugging - it allows us to see that the inferred
type is what we think it should be.  Furthermore, it will allow the IR
reader to avoid complex, operator-specific type inference.

295bb7ff8d ir_print_visitor: Remove unnecessary parenthesis around type names. 
Parenthesis should only be present for compound types (i.e. arrays
or structures).  For atomic types, simply print the symbol.

1f0cb24f8b Print full type for ir_constant instead of base and component count. 
vec4 and mat2x2 have the same base type and number of components;
printing the full type allows us to distinguish the two.

9fa99f3b6c Refactor IR function representation. 
Now, ir_function is emitted as part of the IR instructions, rather than
simply existing in the symbol table.  Individual ir_function_signatures
are not emitted themselves, but only as part of ir_function.

fbc7c0b8f2 Make function bodies rely on the parameter variable declarations. 
Previously, generating inlined function bodies was going to be
difficult, as there was no mapping between the body's declaration of
variables where parameter values were supposed to live and the
parameter variables that a caller would use in paramater setup.
Presumably this also have been a problem for actual codegen.

894ea972a4 Put function bodies under function signatures, instead of flat in the parent. 
This will let us know the length of function bodies for the purpose of
inlining (among other uses).

fad607a9be Add ir_loop to represent loops 
This touches a lot of files because everything derived from ir_visitor
has to be updated.  This is the primary disadvantage of the visitor pattern.

3c6fea3048 Implement ir_if (for if-statments) and conversion from AST 
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.

    shaders/glsl-unused-varying.frag
    shaders/glsl-fs-sqrt-branch.frag

01665262e5 Implement exp2() and log2(), and make ir_unop_exp and ir_unop_log be base e. 
Making the base e functions IR operations is not a clear win.  i965
doesn't support it, it doesn't look like r600 supports it, but r500
does. It should be easily supportable as a lowering pass, though.

44d68fd06f Add sqrt() builtin as an IR operation. 
Following a discussion in #dri-devel, I think this makes more sense
than implementing it as RSQ RCP CMP as Mesa did.  The i965 has a
hardware sqrt that should work, and AMD is suppposed to be able to
implement it as RSQ RCP with an alternate floating point mode so that
the 0.0 case is handled like we want.

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.

8c70a62193 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.
