The actual blocker for precompiled headers is not the iOS/tvOS/watchOS platforms, but the way qmake handled multiple-architecture builds on Apple platforms. This patch allows multi-arch builds to be performed while using precompiled headers. Since df91ef3d6c55692a0236f67b6c6b134a3bf84098 (April 2009), Clang has had support for PCH files in the driver, which allows to use the -include flag to automatically translate to -include-pch. We can then take advantage of the fact that the -include option is allowed to not be separate from its argument, which lets us take advantage of -Xarch to specify a per-architecture precompiled header file. This is done through some magic in the qmake Makefile generator which "multiplexes" the PCH creation rule across multiple architectures and replaces a series of tokens with the proper precompiled header paths and architecture flags at usage point.
