  Changed paths:
    M compiler-rt/lib/asan/asan_rtl_static.cpp
    M compiler-rt/lib/asan/asan_rtl_x86_64.S

  Log Message:
  -----------
  [ASan] Added intermediate functions between assembly and __asan_report.* to avoid link errors.

Instead of calling asan_report.* directly from assembly code they have been replaced with corresponding asan_report.*_asm function, which call asan_report.*. All asan_report.* are now undefined weak symbols, which allows DSOs to link when z defs is used.
