Fix two issues that Eli Friedman pointed out, where would misoptimized code like:
...
char a[200];
init(a, a+200);
OR
int a[200];
char* b = (char*)a;
char* c = (char*)a;
foo(b, c);

Revert r50441. The original code was correct. Add some more comments so that I don't make the same mistake in the future.

Fix a bug in memcpyopt where the memcpy-memcpy transform was never being applied because
...
we were checking for it in the wrong order. This caused a miscompilation because the
return slot optimization assumes that the call it is dealing with is NOT a memcpy.
