Always use binary mode for output stream. This is important to prevent unwanted end of line conversion on Windows. Should not affect Unix where O_BINARY is not defined. This fix /clang/test/lexer/preamble.c XFAIL on WIN32.

Fix zeroExtend and signExtend to support empty sets, and to return the smallest
possible result set which contains the extension of each element in their
inputs. For example zext i8 [100, 10) to i16 is now [0, 256), not i16 [100, 10)
which contains 63446 members.

I wasn't able to convince myself that all GetMainExecutable

This makes it possible to unregister the file from FilesToRemove when

Triple class constructor.  Only valid triples should now be used
inside LLVM - front-ends are now responsable for rejecting or
correcting invalid target triples.  The Triple::normalize method
can be used to straighten out funky triples provided by users.
Give this a whirl through the buildbots to see if I caught all
places where triples enter LLVM.
