nir/opt_if: fix opt_if_merge when destination branch has a jump

Fixes a case where opt_if_merge created code like:
if (...) {
   break;
   loop {
      ...
   }
}
which caused opt_peel_loop_initial_if to complain that the loop pre-header
wasn't a predecessor of the loop header. This patch prevents this
(invalid, I think) unreachable code from being created.

nir: Add a range_base+range to nir_intrinsic_load_ubo().

For UBO accesses to be the same performance as classic GL default uniform
block uniforms, we need to be able to push them through the same path.  On
freedreno, we haven't been uploading UBOs as push constants when they're
used for indirect array access, because we don't know what range of the
UBO is needed for an access.

I believe we won't be able to calculate the range in general in spirv
given casts that can happen, so we define a [0, ~0] range to be "We don't
know anything".  We use that at the moment for all UBO loads except for
nir_lower_uniforms_to_ubo, where we now avoid losing the range information
that default uniform block loads come with.

In a departure from other NIR intrinsics with a "base", I didn't make the
base an be something you have to add to the src[1] offset.  This keeps us
from needing to modify all drivers (particularly since the base+offset
thing can mean needing to do addition in the backend), makes backend
tracking of ranges easy, and makes the range calculations in
load_store_vectorizer reasonable.  However, this could definitely cause
some confusion for people used to the normal NIR base.

nir/lower_io: Fix the unknown-array-index case in get_deref_align

The current align_mul calculation in the unknown-array-index
calculation is

    align_mul = MIN3(parent_mul,
                     min_pow2_divisor(parent_offset),
                     min_pow2_divisor(stride))

which is certainly correct if parent_offset > 0.  However, when
parent_offset = 0, min_pow2_divisor(parent_offset) isn't well-defined
and our calculation for it is 1 << -1 which isn't well-defined.  That
said.... it's not actually needed.

The offset to the base of the array is

    array_base = parent_mul * k + parent_offset

for some integer k.  When we throw in an unknown array index i, we get

    elem = parent_mul * k + parent_offset + stride * i.

If we set new_align = MIN2(parent_mul, min_pow2_divisor(stride)), then
both parent_mul and stride are divisible by new_align and

    elem = (parent_mul / new_alig) * new_align * k +
           (stride / new_align) * new_align * i + parent_offset

         = new_align * ((parent_mul / new_alig) * k +
                        (stride / new_align) * i) + parent_offset

so elem = new_align * j + parent_offset where

    j = (parent_mul / new_alig) * k + (stride / new_align) * i.

That's a very long-winded way of saying that we can delete one parameter
from the align_mul calculation and it's still fine. :-)

radeonsi: kill point size VS output if it's not used by the rasterizer

Fixed-func shaders can contain the output, because their generator
doesn't consider the current primitive type into account.

lima/ppir: Skip instruction merge when having more than one successor

ppir_do_one_node_to_instr merges instructions and uses a pipeline reg
to save a reg. It tests if ppir_node_has_single_src_succ, but it should
check if ppir_node_has_single_succ.

The following deqp tests run into this issue because they have a node
with 2 successors in different blocks, where one was merged into the same
instruction and the second one is pointing to a missing predecessor then.

Fixes the following deqp tests:
dEQP-GLES2.functional.shaders.loops.do_while_dynamic_iterations.vector_counter_fragment
dEQP-GLES2.functional.shaders.loops.for_dynamic_iterations.vector_counter_fragment

swr: Fix crashes on non-AVX hardware

Compilers may use vector instructions in calculating
hash values of std::string. This happens usualy when
high optimalization level is enabled. SWR had two
static std::map<std::string, T> variables which
lead to crashes on non-AVX systems during the initialization

intel/compiler: move extern C functions out of namespace brw

brw_compile_gs and brw_compile_tcs are extern C functions, but are
defined inside of brw namespace, which somehow works but confuses
Eclipse CDT's code analysis.

Move these functions out of brw namespace and fix references to
objects from brw namespace.
