revert my previous patches that introduced an additional parameter to the objectsize intrinsic.
...
After a lot of discussion, we realized it's not the best option for run-time bounds checking

change the objectsize intrinsic signature: add a 3rd parameter to denote the maximum runtime performance penalty that the user is willing to accept.
...
This commit only adds the parameter. Code taking advantage of it will follow.

Reapply address space patch after fixing an issue in MemCopyOptimizer.
...
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

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.
