X86: Do not use llc -march in tests. `llc -march` is problematic because it only switches the target architecture, but leaves the operating system unchanged. This occasionally leads to indeterministic tests because the OS from LLVM_DEFAULT_TARGET_TRIPLE is used. However we can simply always use `llc -mtriple` instead. This changes all the tests to do this to avoid people using -march when they copy and paste parts of tests. See also the discussion in https://reviews.llvm.org/D35287 llvm-svn: 309774

; RUN: not llc -mtriple=i686-- -no-integrated-as < %s 2>&1 | FileCheck %s
Fix handling of the 'n' asm constraint with invalid operands. It had accidently accepted a symbol+offset value (and emitted incorrect code for it, keeping only the offset part) instead of properly reporting the constraint as invalid.
