ir_to_mesa: Start building GLSL IR to Mesa IR conversion.
...
There are major missing pieces here. Most operations aren't
supported. Matrices need to be broken down to vector ops before we
get here. Scalar operations (RSQ, RCP) are handled incorrectly.
Arrays and structures are not even considered.

Make inlined function variables auto, not in/out.

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.

Don't forget to add the declaration of our temporary variable for assigns.

Otherwise, dead code elimination gets confused since it relies on

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.

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.

Use AH_TOP and AH_BOTTOM macros so that the standard include guard
mechanisms are emitted by autoheader into the generated config.h file.

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.

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).
