description:
Removing the requirement of "aligned" attribute support.

Before 0a2a0b5a74f4, the address of values used in runtime had to be the
multiple of 16, because the address of a variable was used as its VM
index. The first 4 bits of an index signified the scope of a varible.

This is no longer the case, after 0a2a0b5a74f4 the address of a variable
is never used as its VM index.
