It does not get removed. It ends up in the final image. It is also redundant
because load and store can also add a 12 bit signed offset.

Simplified:
unsigned _BitInt(2049)
foo (unsigned _BitInt(6384) x, _BitInt(8) y)
{
return x * y;
}
_BitInt(2049)
bar (unsigned _BitInt(6384) x, _BitInt(1023) y)
{
return x * y;
}
