LBOUND and SHAPE runtime were added with an API that avoids making a
dynamic allocation for the small result storage. Update the UBOUND API
that was already there and used in lowering outside of the assumed-rank
case.
Add tests for the assumed-rank case.
Add SHAPE runtime API (will be used for assumed-rank, lowering is
generating other cases inline).
I tried to make it in a way were there is no dynamic allocation in the
runtime/deallocation expected to be inserted by inline code for arrays
that we know are small (lowering will just always stack allocate a rank
15 array to avoid dynamic stack allocation or heap allocation).
Where possible, I added additional information to the messages to help
programmers figure out what went wrong. I also removed all uses of the word
"bad" from the messages since (to me) that implies a moral judgement rather
than a programming error. I replaced it with either "invalid" or "unsupported"
where appropriate.

This change adds runtime routines and tests for LBOUND when passed a DIM argument, SIZE, and UBOUND when not passed a DIM argument.
Associated changes for lowering have already been merged into fir-dev.
