Change tests from "opt %s" to "opt < %s" so that opt doesn't see the
...
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename.

of using llvm-as, now that opt supports this.

enhance memcpy opt to turn memmoves into memcpy when the src/dest
...
don't alias. Remove an old and poorly reduced testcase that fails
with this transform for reasons unrelated to the original test.

Split the Add, Sub, and Mul instruction opcodes into separate
...
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.
For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.
This implements the first step of the plan outlined here:

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);

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.
