This CL continues refactoring aimed at isolating StreamingFlowGraphBuilder.
StreamingFlowGraphBuilder dependency is removed from classes
* StreamingConstantEvaluator (it still depends on FlowGraphBuilder)
* ConstantHelper
* SimpleExpressionConverter
and several methods in object.cc.
StreamingConstantEvaluator and ConstantHelper are moved from
kernel_binary_flowgraph{.h, .cc} to a new source file
constant_evaluator{.h, .cc}. StreamingConstantEvaluator is renamed
to ConstantEvaluator.
KernelFingerprintHelper and KernelSourceFingerprintHelper are moved to
a new source file kernel_fingerprints{.h, .cc}.
Instances of kernel::FlowGraphBuilder no longer contain back reference
to a StreamingFlowGraphBuilder. In order to drop this circular dependency
TranslateFinallyFinalizers() is moved from FlowGraphBuilder to
StreamingFlowGraphBuilder.
