[PATCH 0/4] IBM Z: Store long doubles in vector registers when possible

[Ilya Leoshkevich]

Bootstrapped and regtested on s390x-redhat-linux with --with-mode=zarch
--with-arch=z14.  Ok for master?

This patch series implements storing long doubles in vector registers
on z14+.  Patches 1 and 2 are initial cleanups.  Patch 3 is the actual
implementation, patch 4 adds tests.

Ilya Leoshkevich (4):
  IBM Z: Remove unused RRe and RXe mode_attrs
  IBM Z: Unhardcode NR_C_MODES
  IBM Z: Store long doubles in vector registers when possible
  IBM Z: Test long doubles in vector registers
