Otherwise we may end up trying to coalesce in a case such as
ssa_1 = fadd r1, r2
r3.x = fneg(r2);
r3 = vec4(ssa_1, ssa_1.y, ...)
and that would cause us to move the writes to r3 from the vec to the
fadd which would re-order them with respect to the write from the fneg.
In order to solve this, we just don't coalesce if the destination of the
vec is not SSA. We could try to get clever and still coalesce if there
are no writes to the destination of the vec between the vec and the ALU
source. However, since registers only come from phi webs and indirects,
the chances of having a vec with a register destination that is actually
coalescable into its source is very slim.

On GFX9 whether the buffer size is interpreted as elements or bytes
depends on whether IDXEN is enabled in the instruction. If the index
is a constant zero, LLVM optimizes IDXEN to 0.
Now the size in elements is interpreted in bytes which of course
results in out of bounds accesses.
The correct fix is most likely to disable the LLVM optimization,
but we need something to work with LLVM <= 6.0.
radeonsi does the max between stride and element count on the CPU
but that results in the size intrinsics returning the wrong size
for the buffer. This would cause CTS errors for radv.

When creating a image from a texture, the image's dri_format is
set to the first plane's format, and used to look up for the
fourcc. e.g. for FOURCC_NV12 texture, the dri_format is set to
__DRI_IMAGE_FORMAT_R8, we end up with a wrong entry in function
intel_lookup_fourcc():
{ __DRI_IMAGE_FOURCC_R8, __DRI_IMAGE_COMPONENTS_R, 1,
{ { 0, 0, 0, __DRI_IMAGE_FORMAT_R8, 1 }, } },
instead of the correct one:
{ __DRI_IMAGE_FOURCC_NV12, __DRI_IMAGE_COMPONENTS_Y_UV, 2,
{ { 0, 0, 0, __DRI_IMAGE_FORMAT_R8, 1 },
{ 1, 1, 1, __DRI_IMAGE_FORMAT_GR88, 2 } } },
as a result, a wrong fourcc __DRI_IMAGE_FOURCC_R8 was returned.
To fix this bug, the image inherits the texture's planar_format that
has the original fourcc; Upon querying, if planar_format is set,
return the saved fourcc; Otherwise fall back to the old way.

vec1 32 ssa_603 = phi block_6: ssa_553
vec1 32 ssa_604 = iadd ssa_551, ssa_66
The problem is the phis. Loop unrolling expects the last block in
the loop to be empty once we splice the instructions in the last
block into the continue branch. The problem is we cant move phis
so here we lower the phis to regs when preparing the loop for
unrolling. As it could be possible to have multiple additional
blocks/ifs following the terminator we just convert all phis at
the top level of the loop body for simplicity.
We also add some comments to loop_prepare_for_unroll() while we

terminator but failed to actually unroll the loop, this resulted
