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

If the headermap maps the filename to a framework include ("Foo.h" -> "Foo/Foo.h"), continue header lookup using the framework include as filename. This allows us to conveniently treat #import "Foo.h" as an implicit module import if we can resolve "Foo/Foo.h" as such. rdar://16042979 llvm-svn: 201419

[HeaderSearch] Fix issue where if a headermap entry maps the filename to a framework import (non-absolute path) then we fail to find it if it is re-included later on. rdar://16285490 llvm-svn: 203542
