Log:
S/390: PR79893: Add diagnostics vec_load_bndry builtin.

The boundary argument of the vec_load_bndry builtin needs to be
rewritten.  At that point it must be constant already.  The current
diagnostics in s390_expand_builtins is too late for this.  The patch
adds an additional check for that builtin which will be triggered
already during preprocessing.

Regression tested on s390x.
