RISC-V: Use encoded nelts when calling repeating_sequence_pHEADtrunkmaster

repeating_sequence_p operates directly on the encoded pattern and does
not derive elements using the .elt() accessor. Passing in the length of
the unencoded vector can cause an out-of-bounds read of the encoded
pattern.

gcc/ChangeLog:

	* config/riscv/riscv-v.cc (rvv_builder::can_duplicate_repeating_sequence_p):
	Use encoded_nelts when calling repeating_sequence_p.
	(rvv_builder::is_repeating_sequence): Ditto.
	(rvv_builder::repeating_sequence_use_merge_profitable_p): Ditto.
