[SystemZ] Add TM and TMY

The main complication here is that TM and TMY (the memory forms) set
CC differently from the register forms.  When the tested bits contain
some 0s and some 1s, the register forms set CC to 1 or 2 based on the
value the uppermost bit.  The memory forms instead set CC to 1
regardless of the uppermost bit.

Until now, I've tried to make it so that a branch never tests for an
impossible CC value.  E.g. NR only sets CC to 0 or 1, so branches on the
result will only test for 0 or 1.  Originally I'd tried to do the same
thing for TM and TMY by using custom matching code in ISelDAGToDAG.
That ended up being very ugly though, and would have meant duplicating
some of the chain checks that the common isel code does.

I've therefore gone for the simpler alternative of adding an extra
operand to the TM DAG opcode to say whether a memory form would be OK.
This means that the inverse of a "TM;JE" is "TM;JNE" rather than the
more precise "TM;JNLE", just like the inverse of "TMLL;JE" is "TMLL;JNE".

[InstCombiner] Expose opportunities to merge subtract and comparison.

Several architectures use the same instruction to perform both a comparison and
a subtract. The instruction selection framework does not allow to consider
different basic blocks to expose such fusion opportunities.

Therefore, these instructions are “merged” by CSE at MI IR level.

To increase the likelihood of CSE to apply in such situation, we reorder the
operands of the comparison, when they have the same complexity, so that they
matches the order of the most frequent subtract.

A reference to a scope is more general than a reference to a type since
DIType is a subclass of DIScope.

A reference to a type can be either an identifier for the type or
the DIType itself, while a reference to a scope can be either an
identifier for the type (when the scope is indeed a type) or the
DIScope itself. A reference to a type and a reference to a scope
will be resolved in the same way. The only difference is in the
verifier when a field is a reference to a type (i.e. the containing
type field of a DICompositeType) or a field is a reference to a scope
(i.e. the context field of a DIType).

This is to get ready for switching DIType::getContext to return
DIScopeRef instead of DIScope.

Tighten up isTypeRef and isScopeRef to make sure the identifier is not
empty and the MDNode is DIType for TypeRef and DIScope for ScopeRef.
