Rui Ueyama 3f851704c1 Move new lld's code to Common subdirectory.
New lld's files are spread under lib subdirectory, and it isn't easy
to find which files are actually maintained. This patch moves maintained
files to Common subdirectory.

// This file provides a way to combine bitcode files into one ELF
// file by compiling them using LLVM.
//
// If LTO is in use, your input files are not in regular ELF files
// but instead LLVM bitcode files. In that case, the linker has to
// convert bitcode files into the native format so that we can create
// an ELF file that contains native code. This file provides that
// functionality.
