This patch improves handling of unconditional KILL instructions inside
the conditional blocks, uncovering more opportunities for if-conversion.

PRED_SET instructions that update exec mask should be scheduled immediately
prior to the "if-then-else" block, because any instruction that is
inserted after alu clause with PRED_SET and before conditional block is
also conditionally executed by hw (exec mask is already updated at that
moment).
Propbably it's better to make PRED_SET a part of conditional
"if-then-else" block in the IR to handle this more cleanly,
but for now this temporary solution should prevent the problem.

For compute shaders we need to let the backend know that
GPRs 0 and 1 are preloaded with some compute-specific input
values, otherwise any use of these regs without previous
definition is considered as undefined value and usually
is simply replaced with 0.

We have to assume that all GPRs in compute shader can be indirectly
addressed because LLVM backend doesn't provide any indirect array info.
That's why for compute shaders GPR array is created that covers all used
GPRs (0..r600_bytecode::ngpr-1), but this seriously restricts register
allocation in sb.
This patch checks for actual use of indirect access in the shader and
if it's not used then GPR array is not created, so that regalloc is not
unnecessarily restricted.

It turns out the MI_LOAD_REGISTER_IMM approach doesn't work on Haswell,
and regressed essentially all the transform feedback Piglit tests.
This morally reverts eaa6fbe6d5. However,
the code is still simpler than it was. On BeginTransformFeedback, we
simply flush the batch and set the SOL reset flag so that the next batch
will start with zeroed offsets. There's still no software counting.

Previously uniform blocks allowed for the 'uniform' keyword
to be used with members of a uniform blocks. With interface
blocks 'in' can be used on 'in' interface block members and
'out' can be used on 'out' interface block members.
The basic_interface_block rule will verify that the same
qualifier type is used with the block and each member.

An interface block member may specify the type:
in {
in vec4 in_var_with_qualifier;
};
When specified with the member, it must match the same
type as interface block type.
It can also omit the qualifier:
uniform {
vec4 uniform_var_without_qualifier;
};
When the type is not specified with the member,
it will adopt the same type as the interface block.

Relaxes the validation of
OPTION ARB_precision_hint_{nicest,fastest};
to allow duplicate options. The spec says that both /nicest/ and
/fastest/ cannot be specified together, but could be interpreted
either way for respecification of the same option.
Other drivers (NVIDIA etc) accept this, and at least one Unity3D game
expects it to succeed (Kerbal Space Program).
