This is the best idea I have at the moment...
The attached patch starts to improve the error messages for NEON
intrinsics, by adding %K to the error message string, as suggested by
Jakub a while ago.
========== error message without this patch:

This patch depends on Alan's patch (upthread). If conflicts were
resolved, it could be applied without, but would have no effect.
OK for trunk?
Further clean up (more work like Alan's patch) is needed to address
the other intrinsics which have arguments with constant integer range
constraints (vget_lane/vset_lane/vldN_lane/vstN_lane/shifts. Richard,
Marcus: is such clean up suitable for after stage 1 closes?
