gallivm: Fix Altivec pack intrinsics for little-endian

This patch fixes use of Altivec pack intrinsics on little-endian PowerPC
systems.  Since little-endian operation only affects the load and store
instructions, the semantics of pack (and other) instructions that take
two input vectors implicitly change: the pack instructions still fill
a register placing values from the first operand into the "high" parts
of the register, and values from the second operand into the "low" parts
of the register, but since vector loads and stores perform an endian swap,
the high parts end up at high memory addresses.

To still achieve the desired effect, we have to swap the two inputs to
the pack instruction on little-endian systems.  This is done automatically
by the back-end for instructions generated by LLVM, but needs to be done
manually when emitting intrisincs (which still result in that instruction
being emitted directly).

vc4: Add a CSE optimization pass.

Debugging a regression in discard support was just too full of duplicate
instructions, so I decided to remove them instead of re-analyzing each of
them as I dumped their outputs in simulation.

vc4: Switch to using native integers.

There were troubles with bools without using native integers
(st_glsl_to_tgsi seemed to think bool true was 1.0f sometimes, when as a
uniform it's stored as ~0), and since I've got native integers other than
divide, I might as well just support them.

vc4: Expose compares at a lower level in QIR.

Before, we had some special opcodes like CMP and SNE that emitted multiple
instructions.  Now, we reduce those operations significantly, giving
optimization more to look at for reducing redundant operations.

The downside is that QOP_SF is pretty special -- we're going to have to
track it separately when we're doing instruction scheduling, and we want
to peephole it into the instruction generating the destination write in
most cases (and not allocate the destination reg, probably.  Unless it's
used for some other purpose, as well).

vc4: Stop being so clever in CMP handling.

This kind of cleverness should be in a general merging-of-ADD-and-MUL
instruction scheduler, rather than individual opcodes.

state_tracker: Fix bug in conditional discards with native ints.

A bool is 0 or ~0, and KILL_IF takes a float arg that's <0 for discard or
>= 0 for not.  By negating it, we ended up doing a floating point subtract
of (0 - ~0), which ended up as an inf.  To make this actually work, we
need to convert the bool to a float.

egl: Restrict multiplication in calloc arguments to use compile-time constants

As explained in the previous commit, we want to avoid the possibility of
integer-multiplication overflow while allocating buffers.

In these two cases, the final allocation size is the product of three values:
one variable and two that are fixed constants at compile time.

In this commit, we move the explicit multiplication to involve only the
compile-time constants, preventing any overflow from that multiplication, (and
allowing calloc to catch any potential overflow from the remainining implicit
multiplication).

Eliminate several cases of multiplication in arguments to calloc

In commit 32f2fd1c5d6088692551c80352b7d6fa35b0cd09, several calls to
_mesa_calloc(x) were replaced with calls to calloc(1, x). This is strictly
equivalent to what the code was doing previously.

But for cases where "x" involves multiplication, now that we are explicitly
using the two-argument calloc, we can do one step better and replace:

calloc(1, A * B);

with:

calloc(A, B);

The advantage of the latter is that calloc will detect any overflow that would
have resulted from the multiplication and will fail the allocation, (whereas
the former would return a small allocation). So this fix can change
potentially exploitable buffer overruns into segmentation faults.
