This patch would like to refine the code gen for the bswap16.

From: Pan Li
This patch would like to refine the code gen for the bswap16.
We will have VEC_PERM_EXPR after rtl expand when invoking
__builtin_bswap. It will generate about 9 instructions in
loop as below, no matter it is bswap16, bswap32 or bswap64.
.L2:
1 vle16.v v4,0(a0)
