Stop messing with the 'g' group of options in CompilerInvocation. With this change, most 'g' options are rejected by CompilerInvocation. They remain only as Driver options. The new way to request debug info from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}" and "-dwarf-version={2|3|4}". In the absence of a command-line option to specify Dwarf version, the Toolchain decides it, rather than placing Toolchain-specific logic in CompilerInvocation. Also fix a bug in the Windows compatibility argument parsing in which the "rightmost argument wins" principle failed. Differential Revision: http://reviews.llvm.org/D13221 llvm-svn: 249655

Parse and print DIExpressions inline to ease IR and MIR testing Summary: Most DIExpressions are empty or very simple. When they are complex, they tend to be unique, so checking them inline is reasonable. This also avoids the need for CodeGen passes to append to the llvm.dbg.mir named md node. See also PR22780, for making DIExpression not be an MDNode.
