cmd/compile/internal/ssa: batch up all zero-width instructions
When generating location lists, batch up changes for all zero-width
instructions, not just phis. This prevents the creation of location list
entries that don't actually cover any instructions.
This isn't perfect because of the caveats in the prior CL (Copy is
zero-width sometimes) but in practice this seems to fix all of the empty
lists in std.
