It introduces a new macro specified type "e" for function argument.
"e", followed by the base type and its vector type width is the same as the register size,
is used to specify the argument with the certain base type but its element size depends
on XLen. For example, vector type with base type i8 is v4i8 on RV32 and v8i8 on RV64.

It doesn't include RV64 only intrinsics.
