Revert 259561 "Set the default ASan options for executables buil..."

> Set the default ASan options for executables built with ASan on Linux.
> 
> This is a copy of https://codereview.chromium.org/25687005/ updated for the current trunk
> with the link_dependency attribute speculatively added to base/base.gyp:sanitizer_options

> This CL introduces a module, base/debug/sanitizer_options.cc, which will override
> the defaults for various dynamic tools (only ASan at this moment). For every executable
> built with a dynamic tool this module will be linked into that executable, providing
> weak functions to be called by the tool.
> 
> The existing declaration of __asan_default_options() in chrome/app/chrome_exe_main_gtk.cc
> has been moved into sanitizer_options.cc (now every binary built with GOOGLE_CHROME_BUILD=1
> will have the same options as google-chrome-asan.
> The existing declaration of __asan_default_options() in chrome/nacl/nacl_helper_linux.cc
> has been kept as is, but we had to remove -Wl,-u_sanitizer_options_link_helper to avoid picking sanitizer_options.cc.
> 
> GYP changes for OSX and iOS will be committed separately.
