[VM/Compiler/AOT] Bare instructions 7: Trampolines for out-of-range calls

This CL adds support to the ImageWriter to write opaque blocks of
trampoline bytes

The AOT code relocator is adapted to allow limited range calls and
inserts trampolines if need be. The algorithm tries to minimize the
number of trampolines added, which for small applications will be 0.

The unconditional pc-relative calls have limited range:
  * on ARM (+/-32 MB)
  * on ARM64 (+/-128 MB)

To avoid verbose code for doubly-linked list, this CL adds double_list.h
