Add a hashing routine that handles hashing types. Add a test for hashing the contents of DW_FORM_data1 on top of a type with attributes. llvm-svn: 189862

Make DIE.h a public CodeGen header. dsymutil would like to use all the AsmPrinter/MCStreamer infrastructure to stream out the DWARF. In order to do so, it will reuse the DIE object and so this header needs to be public. The interface exposed here has some corners that cannot be used without a DwarfDebug object, but clients that want to stream Dwarf can just avoid these.

#include "../lib/CodeGen/AsmPrinter/DIEHash.h"
[cleanup] Re-sort all the #include lines in LLVM using utils/sort_includes.py. I clearly haven't done this in a while, so more changed than usual. This even uncovered a missing include from the InstrProf library that I've added. No functionality changed here, just mechanical cleanup of the include order. llvm-svn: 225974

#include "llvm/Support/Debug.h"
Re-sort all of the includes with ./utils/sort_includes.py so that subsequent changes are easier to review. About to fix some layering issues, and wanted to separate out the necessary churn. Also comment and sink the include of "Windows.h" in three .inc files to match the usage in Memory.inc. llvm-svn: 198685
