f66ba4f357 ir_function_inlining: Re-add the "s/return/retval =/" functionality. 
I ripped it out with the cloning changes yesterday, and should have
tested and noticed that there were now returns all over.

1b2bcf7913 Fix variable remapping in function cloning. 
It's (ht, data, key) not (ht, key, data).

4b2d32b5b5 ast_node: Remove empty destructor. 
This wasn't serving any purpose. So delete it.

c42e64099b preprocessor: Initialize a potentially uninitialized variable. 
My current reading of the relevant static functions suggests that last
is never used without being uninitialized, (we only use it if the
expansion function returned non-NULL and the expansion functions
always set it before returning non-NULL).

Apparently gcc isn't coming to the same conclusion. Initializing this
to NULL nicely quites gcc and will guarantee a nice, early segfault if
my anaylsis turns out to be wrong.

726faddda2 preprocessor: Remove dead code _token_list_length 
As gcc noticed, this function is not currently being used. Good-bye.

45cbc08438 preprocessor: Remove dead code _string_list_append_list

60c67e46b1 configure: Ensure that config.h can be safely included multiple times. 
Use AH_TOP and AH_BOTTOM macros so that the standard include guard
mechanisms are emitted by autoheader into the generated config.h file.

a32305a8bd configure: Remove some dead code. 
This block of code is useless because a (nearly-equivalent) assignment
is made immediately after. The only difference is the omission of
-Wunreadchable-code in the assignment being used. Presumably, that was
intended to be -Wunreachable-code (without the first 'd'), but since
this hasn't been being used we just drop it.

a22426dc4c Fix typos of "variable" as "varaible" 
One of these was just in a comment. But ther other was in an enum
tag, (which is apparently not being used anywhere yet).

7fd7104fbb ir_variable: Add some missing initialization to the constructor. 
Thanks to valgrind for noticing this problem.

2731a739d0 Avoid using the RHS of an assignment twice. 
This would fix double-evaluation of assignment RHS expressions,
including possible side effects.

8006576b36 ir_function_inlining: Allow inlining of loops and conditionals. 
The new cloning code handles them.

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.

186e2634bf glcpp: Make standalone binary use preprocess(). 
This prevents the two code paths from getting out of sync.  Also, future
work will need the shader source as a string anyway.

Unfortunately, this copies and pastes load_text_file from main.cpp, with
small changes (support for reading from stdin, talloc).

12a820c9d8 glcpp: Fix "dangerous trailing context" warning. 
Flex couldn't be sure whether "def" and "ndef" were part of the #ifdef
and #ifndef patterns or the trailing context of the #if pattern.

e6ae7afc0c glcpp: Recognize plain "//" as a comment. 
Found in glsl-orangebook-ch06-bump.(frag|vert).  This was resulting in
the comments getting passed through to the main compiler's lexer.

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.
