revert r158660, since Chris has some issues with this patch (namely using code to reprent information only used by the compiler)

Original commit msg:
add the 'alloc' metadata node to represent the size of offset of buffers pointed to by pointers.
This metadata can be attached to any instruction returning a pointer
