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.

Daniel Dunbar cdf9bf7048 make/clang_darwin: Tweak CheckArches function to force the integrated-as and use
the stub SDK to try and ensure we always pick up the right archs when they
should be able to be used.
 - Also, warn when we drop an architecture.

This is a reapplication of r150232 that should stick now that we have the
integrated assembler on for ARM.

Alexander Potapenko 7e07f56811 Introduce __asan_set_error_report_callback() to allow the client program post-process the error reports.
If the callback is set, Report() and Printf() print the reports into a buffer (together with stderr), which is then passed to the client.
