RISC-V: THEAD: Add 5 assembly pseudoinstructions for XTheadVector extension
In order to make it easier to complete the compiler's support for
the XTheadVector extension and to be as compatible as possible
with the programming model of the 'V' extension ([1]), we consider
adding a few pseudo instructions ([2]).
th.vmmv.m vd,vs => th.vmand.mm vd,vs,vs
th.vneg.v vd,vs => th.vrsub.vx vd,vs,x0
th.vncvt.x.x.v vd,vs,vm => th.vnsrl.vx vd,vs,x0,vm
th.vfneg.v vd,vs => th.vfsgnjn.vv vd,vs,vs
th.vfabs.v vd,vs => th.vfsgnjx.vv vd,vs,vs
