Implement Vector-Enhancements Facility 2 for s390x
resolves: https://gitlab.com/qemu-project/qemu/-/issues/738
implements:
VECTOR LOAD ELEMENTS REVERSED (VLER)
VECTOR LOAD BYTE REVERSED ELEMENTS (VLBR)
VECTOR LOAD BYTE REVERSED ELEMENT (VLEBRH, VLEBRF, VLEBRG)
VECTOR LOAD BYTE REVERSED ELEMENT AND ZERO (VLLEBRZ)
VECTOR LOAD BYTE REVERSED ELEMENT AND REPLICATE (VLBRREP)
VECTOR STORE ELEMENTS REVERSED (VSTER)
VECTOR STORE BYTE REVERSED ELEMENTS (VSTBR)
VECTOR STORE BYTE REVERSED ELEMENTS (VSTEBRH, VSTEBRF, VSTEBRG)
VECTOR SHIFT LEFT DOUBLE BY BIT (VSLD)
VECTOR SHIFT RIGHT DOUBLE BY BIT (VSRD)
VECTOR STRING SEARCH (VSTRS)
modifies:
VECTOR FP CONVERT FROM FIXED (VCFPS)
VECTOR FP CONVERT FROM LOGICAL (VCFPL)
VECTOR FP CONVERT TO FIXED (VCSFP)
VECTOR FP CONVERT TO LOGICAL (VCLFP)
VECTOR SHIFT LEFT (VSL)
VECTOR SHIFT RIGHT ARITHMETIC (VSRA)
VECTOR SHIFT RIGHT LOGICAL (VSRL)
v5 -> v6:
* Move fix to #1
* Include max CPU model cleanups
* "target/s390x: add S390_FEAT_VECTOR_ENH2 to qemu CPU model"
-> Take care of compat machines
* "tests/tcg/s390x: Tests for Vector Enhancements Facility 2"
-> Add missing newline to end of header file
-> Resolve simple conflict in Makefile
