having the bitcode writer materialize mdnodes for all the debug location tuples when writing out the bc file and stores the information in a more compact form. For example, the -O0 -g bc file for combine.c in 176.gcc shrinks from 739392 to 512096 bytes. This concludes my planned short-term debug info work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100261 91177308-0d34-0410-b5e6-96231b3b80d8
