This was originally intended to make sure the remap location
was not -1. However the code has changed alot since then,
the location is now never set to -1 and we also handle
components meaning this old assert has been doing comparisions
with the pointer to the array of component data.

If we don't remap and output this code would trample the outputs
read bits.
This fixes a regression in
dEQP-VK.tessellation.shader_input_output.barrier
Fixes: 1c9c42d16b (nir: add varying component packing helpers)

v2: update shader info input/output masks when pack components
v3: make sure interpolation loc matches, this is required for the
radeonsi NIR backend.
v4: 33dca36f4f fixed nir_gather_info to update outputs_read
correct, make sure we also adjust this correctly when
packing components.

The initial helpers add support for removing unused varyings between
stages.
V2:
- Moved the io mask helper function into this file rather than
nir.h so it's not used elsewhere considering it doesn't handle
all corner cases.
- Use bitmask rather than hash table to handle tcs outputs (Ken)
