(Oops, meant to mail this out before hitting the CQ button.)

This is a reland of https://codereview.chromium.org/511163002. This was
previously reverted for breaking the Blink Mac GPU Builder. The error was a link
error in profile_io_data.o, because that object file was not rebuilt even though
a header it depended on changed.

I was unable to determine why this occurred. As far as I can tell, the
dependencies are properly expressed in gyp: the chrome target that
profile_io_data.cc is part of depends on net_with_v8, which depends on net. When
I built with ninja -d explain locally and replicated the buildbot config as
closely as I could (using similar GYP_DEFINES and building the same targets),
ninja correctly detected that a net/ header that profile_io_data.cc used was
changed and correctly rebuilt it.
