Allows command line overrides to be centralized in LLVMTargetMachine.cpp. LLVMTargetMachine can intercept common passes and give precedence to command line overrides. Allows adding "internal" target configuration options without touching TargetOptions. Encapsulates the PassManager. Provides a good point to initialize all CodeGen passes so that Pass ID's can be used in APIs. Allows modifying the target configuration hooks without rebuilding the world. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149672 91177308-0d34-0410-b5e6-96231b3b80d8
