  linux-user: elf: ELF_HWCAP for s390x (2019-06-05 16:48:29 +0200)

----------------------------------------------------------------
Finalize implementation of the "Vector Facility" for s390x TCG. Add it
to the QEMU CPU model, so it is enabled as default.
Also:
- One fix (and one workaround) for the STFLE instruction
- Fix the alignment of vector registers (and change the data type)
- Properly generate ELF_HWCAP for s390x for linux-user
- Use a gvec helper for VECTOR SELECT

----------------------------------------------------------------
