In RVV and vcrypto instructions, the masked and tail elements are set to 1s
using vext_set_elems_1s function if the vma/vta bit is set. It is the element
agnostic policy.

However, this function can't deal the big endian situation. We rename the
function, adding '_le' to the end of the name, to indicate that it only
suits little endian situation.

Given that this is a temporary change (vext_set_elems_1s_le is removed later) 
it's
ok to not bother with the macro identations.
