Takeshi Yoneda 3b4544ee48 compiler: remove embedding of pointers of jump tables (#650) 
This removes the embedding of pointers of jump tables (uintptr of []byte)
used by BrTable operations. That is the last usage of unsafe.Pointer in
compiler implementations.
Alternatively, we treat jump tables as asm.StaticConst and emit them
into the constPool already implemented and used by various places.

Notably, now the native code compiled by compilers can be reusable
across multiple processes, meaning that they are independent of
any runtime pointers.
