Use explicit add_subdirectory's for LLVM target sublibraries instead
...
of testing for its presence at cmake time.
This way the build automatically regenerates the makefiles when a svn
update brings in a new sublibrary.

No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32. In llvm side, i686 and x64 can be treated as similar way.

Instead encode llvm IR level property "HasSideEffects" in an operand (shared

the operand when the instruction is an INLINEASM.
This allows memory instructions to be moved around INLINEASM instructions.
