When commuting a thumb instruction in the size reduction pass, thumb instructions are represented as a bundle and so some operands may be marked as internal. The internal flag has to move with the operand when commuting. This test is sensitive to register allocation so can't specifically check that this error was happening, but so long as it continues to pass with -verify then hopefully its still ok. rdar://problem/20752113 llvm-svn: 236282
