fix Issue 22656 - SSE2 instructions have inconsistent layouts in the …

…disassembler output

This is just whitespace formatting in the output, and whitespace is ignored in the unittests. So adding a test for it is a nuisance, as the tests would all have to change if the whitespace was significant.

This change also removes all tabs from the output, replacing them with a computed number of spaces. This will inure the output against people who like to set their tab spacing to the wrong value.
