commit 055e3b408aefb37a44c336af306f22c356fe321a

Test that uprobes supports "rep ret"
We've made a special case in uprobes to support this sequence, since it
does occur in normal gcc output, so make sure of that. At the same
time, test that we reject other prefixes like "repnz ret", even though
we might be able to support them after more analysis.

uprobes_i386: backport check_legacy_prefix from uprobes2
Without this, we can't give "special" prefixed instructions the
treatment they deserve. (e.g. rep-ret)
