Summary: It fixes the conditions of the `check` function to address `is_collection_add` cases correctly.

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.
Depends on D10851762

Summary:
Sometimes in debug mode, the condition set is too big to print in the
log file. This diff limits the maximum number of conditions to print
as 30.

Summary:
Seems useful to know when we're printing one instruction only, but not when we
print lots of them for readability.

Summary: It tries division on minmax value approximately, rather than just returning infinities. For example, `[0,2+min(6,s)] / 2` returns `[0,4]`.

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.

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: We assume multiplication of 1 is safe. It happens sometimes by multiplying `sizeof(char)`.

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.

Summary:
It avoids raising an exception when unexpected arguments are given to
placement new. We will revert this after fixing the frontend to parse
user defined `new` correctly in the future.
