Expand the preallocated Int range to [-16,255]
Effects as I measured them:
RTS Size: +0.1%
Compile times: -0.5%
Runtine nofib: -1.1%
Nofib runtime result seems to mostly come from the `CS` benchmark
which is very sensible to alignment changes so this is likely over
represented.
However the compile time changes are realistic.
This is related to #16961.
