Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID This is done to avoid odd test failures, like the one fixed in r171243. llvm-svn: 171250

Fix PR5744, a case where we were getting the pointer size instead of the value size. This only manifested when memdep inprecisely returns clobber, which is do to a caching issue in the PR5744 testcase. We can 'efficiently emulate' this by using '-no-aa' llvm-svn: 91004

Add error handling in getInt. Accordingly, update a testcase with a broken datalayout string. Also, we never parse negative numbers, because '-' is used as a separator. Therefore, use unsigned as result type. llvm-svn: 168785
