Rather than redefining the BYTE/SHORT_TO_FLOAT macros, just define new
ones with different names. These macros preserve zero when converting.

Don't assert/die if a VBO is too small. Return zero instead. For
debug builds, emit a warning message since this is an unusual situation
that might indicate that there's a bug in the app.
Note that util_draw_max_index() now returns max_index+1 instead of
max_index. This lets us return zero to indicate that one of the VBOs
is too small to draw anything.

This was only used by the xlib driver to add an alpha channel to the
front/window color buffer. This was no longer going to work well with
the move to direct mapping of renderbuffers.

stencil
For a depthstencil buffer with separate stencil,
intel_renderbuffer::region is null. (The regions are kept in hidden depth
and stencil buffers). Since the region is null, intel_map_renderbuffer()
assumed there was no data and returned a null map pointer, which in turn
was dereferenced (!) by MapRenderbuffer's caller.
This patch fixes intel_map_renderbuffer() to map the hidden depth buffer
through the GTT and return that as the mapped pointer. Also, the stencil
bits are scattered and gathered when needed.

The function already implements 3 cases (map through GTT, blit to
a temporary, and detile stencil buffer to temporary), and a 4th will be
added soon: scatter/gather for depthstencil buffers using separate
stencil. For sanity's sake, this factors each case out into its own
function.

Previously, we would fail to compile the following shader due to a bug
in lazy built-in importing:
#version 130
void main() {
float f = abs(5.0);
int i = abs(5);
}
The first call, abs(5.0), would fail to find a local signature, look
through the built-ins, and import "float abs(float)".
The second call, abs(5), would find the newly imported float signature
in the local shader, and settle for that. Unfortunately, it failed to
search the built-ins for the correct/exact signature, "int abs(int)".
Thus, abs(5) ended up being a float, causing a bizarre type error when
we tried to assign it to an int.
Fixes piglit test builtin-overload-matching.frag.
This is /not/ a candidate for stable branches, as it should only be
possible to trigger this bug using GLSL 1.30's built-in functions that
take integer arguments. Plus, the changes are fairly invasive.

match_function_by_name performs two fairly separate tasks:
1. Hunt down the appropriate ir_function_signature for the callee.
2. Generate the actual ir_call (assuming we found the callee).
Both of these are complicated. The first has to handle exact/inexact
matches, lazy importing of built-in prototypes, different scoping rules
for 1.10, 1.20+, and ES. Not to mention printing a user-friendly error
message with pretty-printed "maybe you meant this" candidate signatures.
The second has to deal with void/non-void functions, pre-call implicit
conversions for "in" parmeters, and post-call "out" call conversions.
Trying to do both in one function is just too unwieldy. Time to split.
This patch purely moves the code to generate an ir_call into a separate
function and reindents it. Otherwise, the code is identical.

When matching function signatures across multiple linked shaders, we
often want to see if the current shader has _any_ match, but also know
whether or not it was exact. (If not, we may want to keep looking.)
This could be done via the existing mechanisms:
sig = f->exact_matching_signature(params);
if (sig != NULL) {
exact = true;
} else {
sig = f->matching_signature(params);
exact = false;
}
However, this requires walking the list of function signatures twice,
which also means walking each signature's formal parameter lists twice.
This could be rather expensive.
Since matching_signature already internally knows whether a match was
exact or not, we can just return it to get that information for free.

We need something that looks like a compiler and not like some hacker
put some functions together. /rant
This is a band-aid for these two problems:
- The R600 and EG control-flow instructions appear in switch statements
next to each other, causing conflicts when adding new instructions.
- The ALU control-flow instructions are bitshifted by 3 (from CF_INST 26:29
to CF_INST 23:29, as is defined by r600 ISA) even for EG, where CF_INST
is 22:29.
To fix this mess, the 'inst' field is bitshifted to the left either by 22, 23,
or 26 (directly in the definitions), such that it can be just or'd when making
bytecode without any shifting. All switch statements have been divided into
two, one for R600 and the other for EG.
Of course, there is a better way to do this, but that is left for future
work.
Tested on RV730 and REDWOOD with no regressions.
v2: minor cleanup as per Alex's comment.

If they were disabled on entry, and we enabled one (like for
BlitFramebuffer), we wouldn't disable it on the way out. Retain the
attempted optimization here (don't keep calling to set each bit for
changes that won't matter) by just setting the bits directly with
appropriate flushing.
