X86: Make fixed register operands ignore register index extensions from the REX prefix. The only cases where this was the correct behavior are now handled with the "B" operand type, and doing things this way was breaking some instructions, notably a shift.

tests: replace all dest ref files on upgrade (if possible). Originally we were copying all source files in, but this caused problems when (large) inputs were copied along with outputs. Then we switched to just copying the standard files (m5stats.txt, etc.) but that was missing things like the *.console files. This fix should catch all the non-standard files too as long as they are copied in manually once when the test is set up. Also get a lot nicer about warning when files are ignored, and warn when expected files are missing. Those new Python sets sure are handy.
