Summary:
For more deduplications of issues, this diff loosens the condition of
similar bounds. The previous condition of similar bounds was too
strict, so [0,0] and [0,+oo] were not similar.

Summary:
This diff preserves values of offset and index separately, rather than
one value of their addition, because premature addition results in
imprecise FPs by the limited expressiveness of the domain.

[inferbo] Check integer overflow when really need
...
Summary:
It avoids checking integer overflow when it definitely cannot happen.
For example, it does not check integer overflow of addition when one
of parameters is a negative number, or underflow of subtraction when
its first parameter is a positive number.

Summary: This diff changes pp of binary operation condition in order to avoid a `make test` failure. For the same `uint64_t` type, it is translated to `unsigned long long` in 64bit mac, but `unsigned long` in 64bit linux, which made a `make test` failure.

[kill -a][1/4] stop using `-a foo` in the infer repo
...
Summary:
Goal of the stack: deprecate the `--analyzer` option in favour of turning
individual features on and off. This option is a mess: some of the options are
now subcommands (compile, capture), others are aliases (infer and checkers),
and they can all be replicated using some straightforward combination of other
options.
This diff: stop using `--analyzer` in tests. It's mostly `checkers` everywhere,
which is already the default. `linters` becomes `--no-capture --linters-only`.
`infer` is supposed to be `checkers` already. `crashcontext` is
`--crashcontext-only`.
