Summary: This adds two new diagnostics: -pass-remarks-missed and -pass-remarks-analysis. They take the same values as -pass-remarks but are intended to be triggered in different contexts. -pass-remarks-missed is used by LLVMContext::emitOptimizationRemarkMissed, which passes call when they tried to apply a transformation but couldn't. -pass-remarks-analysis is used by LLVMContext::emitOptimizationRemarkAnalysis, which passes call when they want to inform the user about analysis results. The patch also: 1- Adds support in the inliner for the two new remarks and a test case. 2- Moves emitOptimizationRemark* functions to the llvm namespace. 3- Adds an LLVMContext argument instead of making them member functions of LLVMContext.
