UBO loads can be boolean-valued expressions, too, so we need to handle
them in emit_bool_to_cond_code() and emit_if_gen6().
However, unlike most expressions, it doesn't make sense to evaluate
their operands, then do something with the results. We just want to
evaluate the UBO load as a whole---which performs the read from
memory---then load the boolean result into the flag register.
Instead of adding code to handle it, we can simply bypass the
ir_expression handling, and fall through to the default code, which will
do exactly that.

Matt and I believe that Sandybridge actually uses 0xFFFFFFFF for a
"true" comparison result, similar to Ivybridge. This matches the
internal documentation, and empirical results, but contradicts the PRM.
So, the comment is inaccurate, and we can actually just handle these
directly without ever needing to fall through to the condition code
path.
Also, the vec4 backend has always done it this way, and has apparently
been working fine. This patch makes the FS backend match the vec4
backend's behavior.

ir_triop_csel can return a boolean expression, so we need to handle it
here; we simply forgot when we added ir_triop_csel, and forgot again
when adding it to emit_bool_to_cond_code.
Fixes Piglit's EXT_shader_integer_mix/{vs,fs}-mix-if-bool on Sandybridge.

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).

BitSet::allocate() is being used with the expectation that it would
leave the bitfield untouched if its size hasn't changed, however,
the function always zeroed the last word, which led to obscure bugs
with live set computation.
This also fixes BitSet::resize(), which was broken, but luckily not
being used.
