When primitive is points, EndPrimitive can't be used to count
primitive. Need to use vertex count instead. And it's also not
needed to do vertex per primitive count and overwrite incomplete

This reverts commit 96fa23bca5.
The correct fix to the problem was a1bc152340, making this
change obsolete as the pass skips any vars marked with
always_active_io. There was no real advantage to allowing these
vars to be split because they can't be removed anyway. Also there
is no way to split varying arrays gracefully here due to the xfb
layout rules, and this change didn't handle arrays at all.
Removing this obsolete code also fixes an assert in the new CTS
test KHR-Single-GL45.enhanced_layouts.xfb_all_stages. The test
was legally adding xfb offsets to all vertex stages but since
we only mark the varyings in the final vertex stage with the
always_active_io flag the other stages were correctly lowering
to scalars but when an array with an offset hit this code it
asserted since it couldn't handle it.

this was implemented thinking that it was returning a boolean value.

Clang unconditionally adds those definitions if using a spirv LLVM target.
That's not a problem on its own, but clang's internal OpenCL header enable
a bunch of OpenCL extensions if those are set.
Lucky for us, we can simply undefine them and spare us the trouble of
finding an upstream solution to this problem :)
This fixes the OpenCL CTS' compiler features_macro test.

Is a phi source is an undef, there's no point in copying it or really
caring about it at all. We would just end up inserting a mov from an
undef to a register. Instead, treat phi sources which point to an undef
as if the phi source doesn't exist.
This also prevents them from being included in phi webs which should
reduce the overall interference seen in the shader. Currently, if two
phis share an undef, their phi webs are consdiered to interfere. By
ignoring undefs we can get rid of this false interference and reduce the
size of phi webs. Reducing the number of things being copied by the
parallel copy instructions should also free up the paralle copy
algorithm and reduce the over-all churn of movs.

Otherwise we will mix and match mesa's custom cross slot packing
with arb_enhanced_layouts style packing and we won't correctly
handle the size of the vars needed for the mesa custom packing.
The code was working correctly if the shader interface had both
a matching input and output but when we only had one side of
the interface we were only marking a single slot location as
packed.
