PTAL.

Flag comparison:
https://build.chromium.org/p/client.v8/builders/V8%20Linux64%20ASAN/builds/14...

https://build.chromium.org/p/tryserver.v8/builders/v8_linux64_asan_rel_ng/bui...

The three cpu profiler failures will be investigated in http://crbug.com/v8/5243
and shouldn't block the switch as we now test ASAN like Chromium does,
apparently signaling other problems.

The flag differences are all similar to other linux builders that already
switched:

    In GN, but not in gyp:
      -fPIC
      -fdebug-prefix-map=/b/build/slave/asan64/build/v8=.
      -fno-ident
      -fno-strict-aliasing
      -fno-threadsafe-statics
      -fsanitize-blacklist=../../tools/memory/asan/blacklist.txt
      -fstack-protector
      -funwind-tables
      -fvisibility-inlines-hidden

    In GN, but not in gyp:
      --param=ssp-buffer-size=4
      -g1
      -gcolumn-info
      -march=x86-64
