[SystemZ] Use LLGT(R) instructions
This adds support for the 31-to-64-bit zero extension instructions
LLGT and LLGTR and uses them for code generation where appropriate.
Since this operation can also be performed via RISBG, we have to
update SystemZDAGToDAGISel::tryRISBGZero so that we prefer LLGT
over RISBG in case both are possible. The patch includes some
simplification to the tryRISBGZero code; this is not intended
to cause any (further) functional change in codegen.
