Revert "x86: Replace evex-no-scale.s with evex-no-scale-[32|64].s"

This reverts commit 19449d7c67, addressing
the issue that was run into back then: There was no relationship to i686-*
and/or cross builds on 64-bit hosts. The sole problem was the use of / as
as comment character in certain ELF targets. Instead of division, use a
comparison operation.

At the same time also revert the ELF related part of 99c2d522f7 ("x86:
Update assembler tests for non-ELF targets") by replacing the construct
that's problematic for non-ELF, and by adding the "#pass" patterns to
the expected output files to cover for the tail padding generated into
COFF output.
