The current ObjectLinkingLayer (now RTDyldObjectLinkingLayer) links objects
in-process using MCJIT's RuntimeDyld class. In the near future I hope to add new
object linking layers (e.g. a remote linking layer that links objects in the JIT
target process, rather than the client), so I'm renaming this class to be more
descriptive.

This patch replaces RuntimeDyld::SymbolInfo with JITSymbol: A symbol class
that is capable of lazy materialization (i.e. the symbol definition needn't be
emitted until the address is requested). This can be used to support common
and weak symbols in the JIT (though this is not implemented in this patch).
For consistency, RuntimeDyld::SymbolResolver is renamed to JITSymbolResolver.
For space efficiency a new class, JITEvaluatedSymbol, is introduced that
behaves like the old RuntimeDyld::SymbolInfo - i.e. it is just a pair of an
address and symbol flags. Instances of JITEvaluatedSymbol can be used in
symbol-tables to avoid paying the space cost of the materializer.

Doing "I++" inside of an EXPECT_* triggers
warning: expression with side effects has no effect in an unevaluated context
because EXPECT_* partially expands to
EqHelper<(sizeof(::testing::internal::IsNullLiteralHelper(MockObjects[I++] + 1)) == 1)>
which is an unevaluated context.

Summary:
Update ObjectTransformLayer::addObjectSet to take the object set by
value rather than reference and pass it to the base layer with move
semantics rather than copy, to match r258185's changes to
ObjectLinkingLayer.
Update the unit test to verify that ObjectTransformLayer's signature stays
in sync with ObjectLinkingLayer's.

Summary:
This is a utility for clients that want to insert a layer that modifies
each ObjectFile and then passes it along to the next layer.
