For th.vmadc/th.vmsbc as well as narrowing arithmetic instructions
and floating-point compare instructions, an illegal instruction
exception will be raised if the destination vector register overlaps
a source vector register group.
To handle this issue, we use "group_overlap" and "enabled" attribute
to disable some alternatives for xtheadvector.
gcc/ChangeLog:
* config/riscv/riscv.md (none,W21,W42,W84,W43,W86,W87,W0):
(none,W21,W42,W84,W43,W86,W87,W0,thv_disabled,rvv_disabled):
Add group-overlap constraint for xtheadvector.
* config/riscv/vector.md:
Disable alternatives that destination register overlaps
source register group for xtheadvector.
