With a couple more constructors that GCC thinks are necessary. Original commit message: [dsymutil] Accept a YAML debug map as input instead of a binary. To do this, the user needs to pass the new -y flag. As it wasn't tested before, the debug map YAML deserialization was completely buggy (mainly because the DebugMapObject has a dual mapping that allows to search by name and by address, but only the StringMap got populated). It's fixed and tested in this commit by augmenting some test with a 2 stage dwarf link: a frist llvm-dsymutil reads the debug map and pipes it in a second instance that does the actual link without touching the initial binary. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@238959 91177308-0d34-0410-b5e6-96231b3b80d8
