fix: add a flag to MapValue and friends which indicates whether any module-level mappings are being made. In the common case of inlining, no module-level mappings are needed, so MapValue doesn't need to examine non-function-local metadata, which can be very expensive in the case of a large module with really deep metadata (e.g. a large C++ program compiled with -g). This flag is a little awkward; perhaps eventually it can be moved into the ClonedCodeInfo class. llvm-svn: 112190
