Bug: http://b/31532493
Using misaligned pointers forces us to potentially take the address of
members in a packed structure (which is now a warning/error in the
latest Clang). Using memcpy() is the proper way to handle this kind of
problem, as the compiler can insert the proper instructions (and usually
elide the memcpy() entirely).
Test: Built correctly with updated compilers.

The compiler will issue the unaligned access instuctions
when reading from a packed struct. Since 'find' takes a
reference, if we pass the field directly it is removed
from its packed context and may be unreadable.
Read the field out directly from the packed struct and pass
in aligned to u_map to fix.
