When evaluating PUSH_G try to tag the reference we are pushing if it's a
constructor. This is potentially helpful for performance and required to
fix #24870.

`compareLength xs n` is a safer and faster alternative to `compare (length xs) n`.
The latter would force and traverse the entire spine (potentially diverging),
while the former traverses as few elements as possible.
The implementation is carefully designed to maintain as much laziness as possible.
As per https://github.com/haskell/core-libraries-committee/issues/257

The following features are applied:
1. Lookup code like Cmm-switches (draft implementation proposed by Sylvain Henry @hsyl20)
2. Nested ifs (logarithmic search vs linear search) (the idea proposed by Sylvain Henry @hsyl20)
