Revert of add new blit2 methods in support of antialiased hairlines guard flag SK_SUPPORT_LEGACY_BLITANTIH2V2 (patchset #2 id:20001 of https://codereview.chromium.org/1060153003/)

Reason for revert:
DEPS roll is failing, one such example:

http://build.chromium.org/p/tryserver.chromium.win/builders/win8_chromium_rel/builds/73847/steps/ash_unittests%20%28with%20patch%29/logs/stdio

This CL was the only CL in the roll when things started to fail.
