Lang Hames ad4a911fea [ExecutionEngine][MCJIT][Orc] Replace RuntimeDyld::SymbolInfo with JITSymbol.
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.

Justin Lebar 0753800383 Fix warning in ObjectTransformLayerTest.
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.

Joseph Tremoulet 23d02f6149 [ORC] Update ObjectTransformLayer signature
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.

Benjamin Kramer 3bdcc8ce8f Don't use std::make_unique.
We still have to support C++11 standard libraries, make_unique is a C++14
feature.
