Ulrich Weigand ebef92169c [SystemZ] Remove most hard-coded R1D instances for sibcalls
Indirect sibling calls need to use %r1 to hold the target address.
This is currently hard-coded in many places.  This is not only
unnecessary, but makes future changes in this area difficult.

This patch now encodes the target address as operand without
hard coding a register in most places throughout the MI back-end.
Code generation still always uses %r1, but this is now decided
solely in one place in SystemZTargetLowering::LowerCall.

NFC intended.

This directory and its subdirectories contain source code for LLVM,
a toolkit for the construction of highly optimized compilers,
optimizers, and runtime environments.

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
documentation setup.

If you are writing a package for LLVM, see docs/Packaging.rst for our
suggestions.
