Re-apply: Add python tool to dump and construct header maps Header maps are binary files used by Xcode, which are used to map header names or paths to other locations. Clang has support for those since its inception, but there's not a lot of header map testing around. Since it's a binary format, testing becomes pretty much brittle and its hard to even know what's inside if you don't have the appropriate tools. Add a python based tool that allows creating and dumping header maps based on a json description of those. While here, rewrite tests to use the tool and remove the binary files from the tree. This tool was initially written by Daniel Dunbar. Thanks to Stella Stamenova for helping make this work on Windows.

[hmaptool] Turn %hmaptool into a proper substitution This is still super ugly, but at least it doesn't require working directories to just line up perfectly for python to find the tool. llvm-svn: 335330

// RUN: %hmaptool write %S/Inputs/headermap-rel2/project-headers.hmap.json %t.hmap
clang-cl: Add a `/showIncludes:user` flag. This flag is like /showIncludes, but it only includes user headers and omits system headers (similar to MD and MMD). The motivation is that projects that already track system includes though other means can use this flag to get consistent behavior on Windows and non-Windows, and it saves tools that output /showIncludes output (e.g. ninja) some work. implementation-wise, this makes `HeaderIncludesCallback` honor the existing `IncludeSystemHeaders` bit, and changes the three clients of `HeaderIncludesCallback` (`/showIncludes`, `-H`, `CC_PRINT_HEADERS=1`) to pass `-sys-header-deps` to set that bit -- except for `/showIncludes:user`, which doesn't pass it.
