Add new relocation type WASM_MEMORY_SIZE_REFERENCE, use relocatable pointers to update wasm memory size references in generated code.
 - Add new RelocInfo mode WASM_MEMORY_SIZE_REFERENCE in the assembler and add relocation information to immediates in compare instructions.
 - Use relocatable constants for MemSize/BoundsCheck in the wasm compiler

 - New RelocInfo mode WASM_MEMORY_REFERENCE as a marker for wasm code objects that need to be relocated on a heap change
 - RelocInfo mode recorded for immediates that use the memory buffer as base
 - Tests to verify address patching works
