This hooks up detection for the "-arch" flag on Mac to set the GYP "ARCH" xcode variable. GN then removes the -arch argument from the compiler args, since GYP will then re-add it based on the ARCH value. Previously, not doing this resulting in mutliple "-arch" arguments to the compiler since GYP would always insert its own.
Disables some warnings on Windows for the re2 target to match the GYP build. The third warning (4018) that the GYP build sets is disabled globally so there's no need to do it for this target.
Hooks up some iOS SDK stuff.

Adds arm version and some android configuration build flags.
This adds most of the logic from common.gypi to the Android GN build.
This is currently missing the crtbegin/end stuff and won't actually make real Android builds. The logic in this patch is just the initial conversion that will require testing and several more passes of fixes.
