Alexander Potapenko 83a689887e Handle two-byte short jumps in the relocated code. 
After the instructions are moved to the branch island, fixupInstructions() expands every 2-byte ja/je instruction with a 1-byte offset into a 6-byte ja/je with 32-bit offset. The offset is fixed to point to the original function.

Evgeniy Stepanov 823085a8f4 [asan] Support for %z to Printf() 
At the moment, asan internal Printf() uses %l modifier for printing
values of size_t and related types. This works, because we control
both the implementation of Printf and all its uses, but can be a
little misleading.

This change adds support for %z to Printf(). All callers that print
sizes and pointers as integers are switched to %zu / %zx.
