Fix out-of-bounds access in regexp inclusion test (#3242)

If `re.*(re.allchar)` was at the end of a regular expression
concatenation, the regular expression inclusion test could cause
out-of-bound accesses. For `re.*(re.allchar)`, we were blindly adding
the index after it to the set of indices being considered. Later in the
loop, we were assuming that all the indices are smaller than the number
of components in the concatenation, thus leading to out-of-bound
accesses. This commit adds a check before adding the index to the set of
indices.
