The UNSPEC_XTHEAD* macros ended up in the unspecv enum,
which broke gcc/testsuite/gcc.target/riscv/xtheadfmv-fmv.c.
The INSNs expect these unspecs to be not volatile.
Further, there is not reason to have them defined volatile.
So let's simply move the macros into the unspec enum.

With this patch we have again 0 fails in riscv.exp.

gcc/ChangeLog:

	* config/riscv/riscv.md: Move UNSPEC_XTHEADFMV* to unspec enum.

Yeah, that should be put in unspec rather than unspecv, LGTM :)
