Reland r332885, "CodeGen, Driver: Start using direct split dwarf emission in clang." As well as two follow-on commits r332906, r332911 with a fix for test clang/test/CodeGen/split-debug-filename.c. llvm-svn: 333013

// REQUIRES: x86-registered-target
DebugInfo: Add flag to CU to disable emission of inline debug info into the skeleton CU In cases where .dwo/.dwp files are guaranteed to be available, skipping the extra online (in the .o file) inline info can save a substantial amount of space - see the original r221306 for more details there. llvm-svn: 279651

// RUN: %clang_cc1 -debug-info-kind=limited -split-dwarf-file foo.dwo -S -emit-llvm -o - %s | FileCheck %s
Move Split DWARF handling to an MC option/command line argument rather than using metadata Since Split DWARF needs to name the actual .dwo file that is generated, it can't be known at the time the llvm::Module is produced as it may be merged with other Modules before the object is generated and that object may be generated with any name. By passing the Split DWARF file name when LLVM is producing object code the .dwo file name in the object file can match correctly. The support for Split DWARF for implicit modules remains the same - using metadata to store the dwo name and dwo id so that potentially multiple skeleton CUs referring to different dwo files can be generated from one llvm::Module. llvm-svn: 301063
