evas/cpu: rework SIGILL code for non-x86 (and fix windows build)

Summary:
the previous patch which improved this code for x86 archs broke compiling
for non-x86 and, coincidentally, for windows builds on x86 due to some
unusual #ifdef blocks

this attempts to restore handling on non-x86 and adds additional #ifdefs for
functions which did not build on windows due to removed code
