* Change the x86 assembly output to use tab characters to separate theDan Gohman2007-07-315-1117/+1117
| | | | | | | | | mnemonics from their operands instead of single spaces. This makes the assembly output a little more consistent with various other compilers (f.e. GCC), and slightly easier to read. Also, update the regression tests accordingly. llvm-svn: 40648
