Krzysztof Parzyszek 7725e497d1 [TableGen] Replace InfoByHwMode::getAsString with writeToStream 
Also add operator<< for use with raw_ostream to InfoByHwMode and its
derived classes.

Recommitting r313989 with the fix for unresolved references: explicitly
define the operator<< in namespace llvm.

Krzysztof Parzyszek 779d98e1c0 TableGen support for parameterized register class information 
This replaces TableGen's type inference to operate on parameterized
types instead of MVTs, and as a consequence, some interfaces have
changed:
- Uses of MVTs are replaced by ValueTypeByHwMode.
- EEVT::TypeSet is replaced by TypeSetByHwMode.

This affects the way that types and type sets are printed, and the
tests relying on that have been updated.

There are certain users of the inferred types outside of TableGen
itself, namely FastISel and GlobalISel. For those users, the way
that the types are accessed have changed. For typical scenarios,
these replacements can be used:
- TreePatternNode::getType(ResNo) -> getSimpleType(ResNo)
- TreePatternNode::hasTypeSet(ResNo) -> hasConcreteType(ResNo)
- TypeSet::isConcrete -> TypeSetByHwMode::isValueTypeByHwMode(false)

For more information, please refer to the review page.
