Working on reconciling out-of-tree patches to compiler-rt for building for iOS.
Summary:
This is one of many changes needed for compiler-rt to get it building on iOS.
This change ifdefs out headers and functionality that aren't available on iOS, and adds support for iOS and the iOS simulator to as an.
Note: this change does not enable building for iOS, as there are more changes to come.
