[PATCH 21/31] VAX: Remove EXTV/EXTZV/INSV instruction use from aligned case insns

2020-11-19 Thread Maciej W. Rozycki
The INSV machine instruction is the only computational operation in the VAX ISA that keeps condition codes intact. In preparation to MODE_CC transition keep patterns apart then that make or do not make use of said instruction. For consistency update EXTV and EXTZV instruction uses accordingly.
