Daniel Sanders 7813ae879e Replace string GNU Triples with llvm::Triple in MCAsmInfo subclasses and create*AsmInfo(). NFC. 
Summary:
This is the first of several patches to eliminate StringRef forms of GNU
triples from the internals of LLVM. After this is complete, GNU triples
will be replaced by a more authoratitive representation in the form of
an LLVM TargetTuple.

Ulrich Weigand bd039299c0 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.

Rafael Espindola ad33dd2914 Move getNonexecutableStackSection up to the base ELF class. 
The .note.GNU-stack section is not SystemZ/X86 specific.

Rafael Espindola d610ba99cb Remove HasLEB128. 
We already require CFI, so it should be safe to require .leb128 and .uleb128.

Rafael Espindola 43c4e24fad Add a MCAsmInfoELF class and factor some code into it. 
We had a MCAsmInfoCOFF, but no common class for all the ELF MCAsmInfos before.

Ulrich Weigand 5f613dfd1f [SystemZ] Add back end 
This adds the actual lib/Target/SystemZ target files necessary to
implement the SystemZ target.  Note that at this point, the target
cannot yet be built since the configure bits are missing.  Those
will be provided shortly by a follow-on patch.

This version of the patch incorporates feedback from reviews by
Chris Lattner and Anton Korobeynikov.  Thanks to all reviewers!

Patch by Richard Sandiford.

Evan Cheng a83b37a9db Move some parts of TargetAsmInfo down to MCAsmInfo. This is not the greatest 
solution but it is a small step towards removing the horror that is
TargetAsmInfo.
