S/390: Improve support of 128 bit vectors in GPRs · 9d605427

This patch improves the handling of 128 bit vectors residing in GPRs
by adding more alternatives to the move pattern.

Regression tested on s390x.

S/390: PR79904: Disallow reg + sym_ref literal pool addresses. · 085db63d

We accept reg + sym_ref as valid address if sym_ref is a literal pool
reference knowing that it will be rewritten as r13 + reg + offset.
However, annotate_constant_pool_refs was never able to handle that.

With the patch only single sym_refs are accepted.

S/390: PR79893: Add diagnostics vec_load_bndry builtin. · dc4f29bc

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.
