Add new parameter to vec_perm_const hook for specifying operand mode.
The rationale of the patch is to support vec_perm_expr of the form: lhs = vec_perm_expr<rhs, mask> where lhs and rhs are vector types with different lengths but have same element type. For example, lhs is SVE vector and rhs is corresponding AdvSIMD vector. It would also allow to express extract even/odd and interleave operations with a VEC_PERM_EXPR. The interleave currently has the issue that we have to artificially widen the inputs with "dont-care" elements. gcc/ChangeLog: * target.def (vec_perm_const): Define new parameter op_mode and update doc. * doc/tm.texi: Regenerate. * config/aarch64/aarch64.cc (aarch64_vectorize_vec_perm_const): Adjust vec_perm_const hook to add new parameter op_mode and return false if result and operand modes do not match. * config/arm/arm.cc (arm_vectorize_vec_perm_const): Likewise. * config/gcn/gcn.cc (gcn_vectorize_vec_perm_const): Likewise. * config/ia64/ia64.cc (ia64_vectorize_vec_perm_const): Likewise. * config/mips/mips.cc (mips_vectorize_vec_perm_const): Likewise. * config/rs6000/rs6000.cc (rs6000_vectorize_vec_perm_const): Likewise * config/s390/s390.cc (s390_vectorize_vec_perm_const): Likewise. * config/sparc/sparc.cc (sparc_vectorize_vec_perm_const): Likewise. * config/i386/i386-expand.cc (ix86_vectorize_vec_perm_const): Likewise. * config/i386/i386-expand.h (ix86_vectorize_vec_perm_const): Adjust prototype. * config/i386/sse.md (ashrv4di3): Adjust call to vec_perm_const hook.
