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.

Better heuristic for str.code/re.range (#3220)
To make sure that our `str.code` function is injectve (except for -1 in
the codomain), we send the inference that `str.code(x) == -1 v
str.code(x) != str.code(y) v x == y` for each pair of `str.code` terms.
Because of the order of disjuncts, `str.code(x) != str.code(y)` was
usually assigned true. This in turn lead to a difficult problem for the
arithmetic engine if there were more `str.code` applications than the
size of the domain. E.g. if we had `0 <= str.code(xi) < 10` for 0 <= i
<= 10, then the arithmetic engine had a difficult time finding a
conflict. This PR improves the heuristic by setting the phase of
`str.code(x) != str.code(y)` to false, so we prefer to keep the
`str.code` values equal instead of trying to make them different.
This change is also reflected in the models produced for inputs
involving `str.code`: Previously, we were producing models with
different values for the `str.code` whereas now the models are much more
uniform.
The PR adds two regressions, one testing `str.code` performance directly
and one testing it for `str.code` terms generated by `re.range`.

Infer conflicts based on regular expression inclusion (#3234)
We have a conflict if we have `str.in.re(x, R1)` and `~str.in.re(x, R2)`
and `R2` includes `R1` because there is no possible value for `x` that
satisfies both memberships. This commit adds code to detect regular
expression inclusion for a small fragment of regular expressions: string
literals with single char (`re.allchar`) and multichar wildcards
(`re.*(re.allchar)`).
