Ulrich Weigand 81d2500685 Use the integrated assembler as default on SystemZ
This was already done in clang, this commit now uses the integrated
assembler as default when using LLVM tools directly.

A number of test cases deliberately using an invalid instruction in
inline asm now have to use -no-integrated-as.

; Test the "S" asm constraint, which accepts addresses that have a base

call void asm "blah $0", "=*S" (i64 *%addr)

; FIXME: at the moment the precise constraint is not passed down to
; target code, so we must conservatively treat "S" as "Q".
