I don't understand why this technique can't solve all of the testing
problems.

Surely, the size of block, number of instructions, size of constant island,
and everything else that makes this big should be a named constant? Make
those constants actually flags that can be changed within a regression
test. Then you can have 8 byte constant islands inside of a 4 instruction
basic block?
