Subject: [PATCH 1/6] [core] use memcpy instead of hand rolling aligned cases
 Hand rolling memcpy like this is always frowned upon because the compiler has
 more insight on whats going on (plus the code resolves to a worse version of
 itself on assembly). This removes some branches that are just straight up
 redundant. May save stuff especially for systems without fastmem enabled.

Subject: [PATCH 5/6] [core] use memcpy instead of hand rolling aligned cases
 Hand rolling memcpy like this is always frowned upon because the compiler has
 more insight on whats going on (plus the code resolves to a worse version of
 itself on assembly). This removes some branches that are just straight up
 redundant. May save stuff especially for systems without fastmem enabled.
