Fix LTO on Linux by not specifying a blacklist.

Fix LTO on Linux by not specifying a blacklist.

The new Clang toolchain rolled yesterday makes LTO devirtualization
working on visibility basis, instead of being based on a blacklist.
This CL just removes the now unsupported option.

You also need to remove from gyp.

I usually wait a day or two after landing things depending on a clang roll --
sometimes it takes a while for regressions to surface.

Hi Nico,

I accept the chance that the toolchain will be reverted. I just want to see if
the compile time regression (https://crbug.com/601822) is resolved by the push,
as expected.
Also, we have a buildbot red which this CL will fix. The worst what would happen
if the toolchain is reverted, that buildbot will become red. Well, I am not
scared!

fair enough, lgtm then :-)
