[PATCH] Working on reconciling out-of-tree patches to compiler-rt for building for iOS.

[Chris Bieneman]

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.

Note: this change does not enable building for iOS, as there are more changes to come.
